TL;DR from Wikipedia: In photon upconversion, two or more incident photons of relatively low energy are absorbed and converted into one emitted photon with higher energy.
Basically photons are combined into a photon that is nearer in wavelength to visible light.
Aww that’s disappointing, but I’m not surprised. Otherwise we’d be using this tech to help colorblind people tell the difference between red and green.
