Autor: Roman, Benjamin J., Villegas, Noel Mireles, Lytle, Kylie, Sheldon, Matthew T.

One photon up-conversion photoluminescence is an optical phenomenon whereby the thermal energy of a fluorescent material increases the energy of an emitted photon compared with the energy of the photon that was absorbed. When this occurs with near un
