IR Lasing Gold

[Seden]

I was reading this article on Nanotechweb.org (Sept.12,2007) entitled "When gold shines even brighter" and thought of Estebans IR Remote sensor. Don't know in any way if there's a relation but heres the link to the article:

http://nanotechweb.org/cws/article/lab/31120

and a quote from it "Excitation of films with the 795 nm fundamental of a Ti:sapphire femtosecond laser produces a strong white luminescence." The films from the quote are gold films. Now when you read it you will notice that there was some tuning involved depending on the thickness I believe but pretty interesting none the less.

Also speaking of IR, I've been following a thread on the Treasurenet Forum under "Techniques" whereby a fellow claims to use a camera with an IR filter to photograph ions on the earths surface at close range where metal has been buried for some time,anyone try this? I went an bought a IR longpass filter and tried photographing an area on my lawn where for the past 11 years I have been dumping my concentrates from placer mining and nada darn thing appeared on the IR picture no matter how I adjusted the settings on the GOOGLE Picassa software.

Comments on either or both?

Hmmmm...
I see the words "excitation", "gold" and "tuning" all came from the same article. This pretty much proves that gold has a frequency that can be tuned to, and that LRLs will locate the gold at distance. Doesn't it?

There is a much easier way to obtain instant results using an old digital camera. Digital cameras are sensitive to IR on their image sensors. In order to remove unwanted IR that spoils pictures, manufacturers put an IR filter over the image sensor. You can disassemble an old digital camera and remove the IR filter from the image sensor, then replace it with a visible light filter that passes IR. This has been done by hobbyists, using a visible light filter made from a piece of 35mm negative film that has been developed. They cut a piece of film from the opaque end of the negative roll of film, and use it to stop visible light, while passing IR.
You can see some details on how to do this online: http://geektechnique.org/index.php?id=254

The advantage to using a modified digital camera is you get instant results, and save the cost of filters, developing and printing, This means the digital camera can be used as a view port to look for sources of IR in relation to buried treasures. No need to wait for prints to be made.

P.S. Gold or gold concentrates dumped on the surface of the ground will not generate ions as gold buried beneath the ground. Scientists have discovered that gold ions are formed below the surface where gold-digesting microorganisms live and attack the gold with chemicals. These ions migrate upward through the soil until they reach 10-30cm below the surface. At this point, the ions become bound with the constituents of the soil (gold compounds, as in metallic gold, gold tellurides, or possibly organic compounds in extremely small amounts). Since your tailings never spent much time in contact with soil at the ion-generating depths, I doubt it has any ions around it. In fact, your IR photos proved it does not show an IR anomaly.

That would explain it

JPlayer,

I didn't remove the filter from my camera so thanks for explaining this. I paid and downloaded a book this englishman wrote on using IR to detect the soil signature of long buried items and the pictures looked very convincing so will have to buy an old camera and take out the IR blocking filter. Yeah I remember now why they did that. Guy's discovered that they could take pictures of clothed women and see beneath them,that was quite a hoot! I guess that would lend new meaning to the phrase "He undresses me with his eyes"

The book is entitled "Discovering Treasure Auras in the Digital Age by David Villanueva" which will set you back $19 to download,but a good read and interesting.

Why do I get the feeling that a new "off topic" thread is about to start?

I made this experiment: put an old IR shielded module into a plastic tube. I use at level of soil 30-40 cm and obtain signal of site just other pistols beeps, so the object emits!

Would not it be more productive just to search treasures instead o selling book telling how to do it?

Only if the technique really works.

Good point!

Reminds of the LRL/MFD concept and contraptions. If finding treasure with paint roller handles actually worked; wouldn't it be more lucrative to just use them - rather than trying to sell them to the gullible and technically-challenged???

Of course let's not forget... a paint roller handle does find treasure, exactly ONCE! When your money is deposited into the Wallet-miner's bank account.

After that, the paint roller handle is just a piece of scrap metal, having all the same treasure locating possibilities as random digging.

You're Right JPlayer!

Just as you predicted this thread started going south with the usual crowd. Esteban thank you for sharing that information as you are one of the very few on Geotech that actually designs and builds things where others in their arm chairs just tap away on the keyboard with sarcastic comments.

Gentlemen,what do you think about the article I posted at the start of this thread from Nanotech.org? Did you READ it? Yes,no maybe,gonna do it?

Nice part about it is it's pure science. I really want your input that's why I posted it.

Randy, thanks. Is more easy create sarcastic comments.

Hi Randy,
I am going to sit in my armchair in front of the computer and watch to see who does something significant. The obvious answer is to get out that old digital camera and disassemble it, then remove the IR filter and replace it with a piece of 35mm exposed film. Then go out and see what you find in the treasure fields.

However, my free time is limited. I have visions of dismantling a digital camera and hearing a "pop" noise when I accidentally short the flash tube capacitor against the cpu in the camera (I already did this on my last attempt). So I sit in my armchair, ever so patiently waiting for some dedicated hobbyist to post their progress on modifying a digital camera and finding interesting IR images in the treasure fields.

P.S. Kudos to Esteban... Marathon designer and builder of experimental electronic treasure machines.

Best wishes,

IR lasing

JPlayer,

I don't have an old digital camera unfortunately. However regarding the nanotech article, I'm going to ebay and see about getting a laser diode. I've seen them at 750+808nm offered and I'd go for the 808nm first. Got to be careful with the budget as my work hours are getting cut starting in a week (10% cut in pay) and the Mrs. has given specific orders to cool it with the VISA. So when I get the laser and experiment with it will let you know how it goes.

Hi Randy,
I read that article. It doesn't say much about how this principle can be used in a practical manner for treasure hunting. The immediate use that comes to mind is in biological imaging.

However, the article states that a 795 nm Ti:sapphire laser can cause thin films of gold to produce luminescence. These films are produced by a sol-gel spin-coating technique and subsequent annealing at 300 °C or, alternatively, near-infrared (NIR) femtosecond laser irradiation. It seems to me that these are laboratory conditions that are suitable for studying these effects. After the laboratory testing is done, then I expect practical methods will be developed to use this illuminescence in the field of biology in connection with tissue evaluations. The laboratory conditions mentioned in the article involve the sol-gel spin-coating technique. Is it possible that this spin-coating technique translates into conditions found in the dirt from buried treasuure? Not sure about that. I do not think there will be any significant application in the treasure hunting field.

But I may be wrong about this. Perhaps Esteban or others have already perfected the engineering details to cause a glow on the surface of the soil where gold is buried.

Thank God for ebay

Jplayer,

I found an 5mw 808nm laser diode with focus capability for $29.50+shipping so will soon find out. I have raw placer gold as well as some I've refined to experiment with.

And if it doesn't work out-so what? On to the next project.

When you place things in an "open forum" that are obviously fringe technology, having nearly zero validity; you can expect to get many different kinds of comments. They might come from folks in armchairs or in my case from a laptop as I fly over the Atlantic.

The point is, if you were only desirous of comments in support of what you posted, perhaps you should consider forums that are moderated more tightly and only cater to the esoteric, occult and fringe technology topics.
