RE: [Vo]:A123 Systems rescued by China's Wanxiang
Terry, What about being able to change the color (frequency) of the emitted photons after the chip has been made? I need to clear this up, but the inventor said that the color could be changed, from IR, thru the visible and into the UV by just reprogramming. I scanned the OLED wiki but did not catch any statement about changing wavelength or frequency. Did I miss it? -Mark -Original Message- From: Terry Blanton [mailto:hohlr...@gmail.com] Sent: Friday, August 17, 2012 6:21 AM To: vortex-l@eskimo.com Subject: Re: [Vo]:A123 Systems rescued by China's Wanxiang Technically, not a LED: http://en.wikipedia.org/wiki/OLED seems to meet your description 'cept for the intensity.

Thanks for finding that Terry... still seems as if color change for semiconductor-based light generation is still 'in the lab'. That's good news! -Mark -Original Message- From: Terry Blanton [mailto:hohlr...@gmail.com] Sent: Friday, August 17, 2012 10:15 AM To: vortex-l@eskimo.com Subject: Re: [Vo]:A123 Systems rescued by China's Wanxiang Color change is cutting edge: http://arstechnica.com/science/2012/07/researchers-pave-way-for-much-brighte r-oleds/ T
Re: [Vo]:A123 Systems rescued by China's Wanxiang
wasn't A123 the builder of efficient LiFePO4 accumulators, good candidate for rough accumulators, less dangerous (don't explode, or burn), near as efficient, especially on duration... I don't understand why LiFePO4 does not get success. it is easy technology, easier to use than LiPoly or LiIon+Co 2012/8/17 MarkI-ZeroPoint zeropo...@charter.net I heard about the Chinese bailout of A123 from a business man I know… ** ** On another note, I stopped by his office late morning to chat, and I brought my watts-up energy meter to verify a new type of light that he showed me last time I visited him. It is some kind of semiconductor-based ‘chip’, ~1 inch square, puts out a blinding 500W-equivalent of light, yet on the watt meter, it started out at 40W, and settled to about 35.8W after an hour – only gets a bit warm, and if you put your hand in front of the light-square, ~6 inches away, you feel pretty much nothing. Briefly chatted with inventor by phone a few weeks ago and he claims it is not LED… OK, I’m intrigued! Then when he claims that he can change the wavelength by simply adjusting a ‘chip’ inside, I had some additional questions…. Like, you mean, after the thing is assembled, you can adjust the wavelength? Anyone hear of something like that? Yeah, there are all different colors of LEDs, but the wavelength is set, immutable when they ‘come out of the oven’… I can’t take a green LED and by tweaking the driving circuit, change its color… or am I missing something here? ** ** -Mark ** **
