What chem reactn gives the highest rate of photons emssn/t ?

AI Thread Summary
The discussion centers on identifying chemical reactions that emit the highest rate of photons per unit time. Oxidation of magnesium and thermite reactions are noted for their significant light emission, primarily due to incandescence from hot metals. Additionally, reactions that produce electronically excited molecules, such as those in flames, also contribute to photon emission, with hydrogen-oxygen flames producing UV light. Chemical lasers, like the HF laser and COIL, are highlighted for their ability to convert chemical energy into substantial photon output. Overall, various chemical reactions can produce light, but specific conditions and mechanisms determine their efficiency in photon emission.

I was trying to google it, but coudn't find any specific answer. Oxidation of Magnesium, for example, emits a lot of light. Is there a table of reactions by high much light they create ?

What chemical reaction emits the highest number of photons per unit per time ? Thank you.

There are all sorts of chemical reactions that emit photons. I believe that in things like magnesium combustion, the thermite reaction, etc. the light is coming from incandescence -- essentially really hot metals glowing. Some reactions emit light, kind of as a side product, when electronically excited molecules/atoms are produced -- flames are an example of this -- the blue flames of gas stoves coming from electronically excited C2 and CH molecules being produced in the mix. Hydrogen-oxygen flames don't give off much visible light, but produce a lot of UV light emission from electronically excited OH molecules emitting light. The chemical reaction in the abdomen of fireflies is another example of photons being produced in a chemical reaction.

Chemical lasers can emit a great deal of their stored chemical potential energy as photons. The HF laser produces infrared emission when hydrogen and fluorine gases react in a resonator cavity.http://en.wikipedia.org/wiki/Hydrogen_fluoride_laser

The US Air Force is working on a chemical laser: COIL (Chemical Oxygen Iodine Laser) which involves lasing on a transition in Iodine. http://en.wikipedia.org/wiki/Chemical_oxygen_iodine_laser

Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
