hello!
I am trying to make a device that will improve reproduction rates in certain microorganisms that I am studying. They reproduce fastest under shorter wavelengths, specifically best at blue light. Any ideas for devices or materials that could help out would be appreciated! An idea I had was to use crystals, specifically Neodymium-doped yttrium orthovanadate, which can split an infrared wavelength in half and make it green (i think). I can use the material under the sun to turn all the higher wavelengths into lower to preserve the same light energy, but convert it into lower wavelengths. Issues: not sustainable, probably expensive. Any other similar ideas or ways I can improve on my idea? thanks!

Infrared is the low-energy end of the spectrum, ultraviolet is the high-energy end. You can down-convert UV to visible light, but not easily up-convert IR to visible.
