The production of light of various wavelengths using IR phosphor down conversion techniques using existing LED emissions to pump sensitizer-rare earth ions that emit at other wavelengths. A sensitizer absorbs an LED chip pump emission and then transfers that energy with high quantum efficiency to dopant ions that then emits at their characteristic wavelength.
