Light without heat: new or old stuff?
A press release states: Nano Chemical Systems Holdings, Inc. announced Jan. 23 that it has filed a US Patent application on a breakthrough new material that exhibits light (luminescent) in the absence of heat. This Nano-enhanced material sets a new standard for high efficiency and for increased brightness.
The press release also states:
Chemiluminescence is the production of light from a non-heat-generating chemical reaction; in short, light without fire. The firefly's biochemical chemiluminescent reaction is highly efficient, approaching the theoretical limit of one photon produced for each molecule involved in the reaction, producing 88 photons for each 100 molecules for a yield of 88%. Current man-made chemiluminescence uses chemical reactions that require a fluorescent molecule, a key intermediate, and a catalyst. They produce sustainable, instantaneous, highly visible light which, with specific doping, can allow for differing colors and intensities. Commercially valuable, man-made chemiluminescent reactions have efficiencies of only 23%.
The Company's present invention improves the efficiency of the reaction for making a chemiluminescent material whose chemo-fluorescent reaction's active period is controllable as a first-order function of humidity, thus reducing to a second order function the prior art's dependency on ambient temperature. The light emitted is intensified by using Nano-materials to achieve new level of brightness. But most amazingly, the material disappears after emitting light for as long as a 2-hour period, leaving almost no residue. Applications for this new, nano-enhanced material cut across industry lines and the Company plans to announce the introduction of the first commercial product based on this technology in the very near future.
