Overview of Photoluminescence Simulation in OpticStudio

Photoluminescence is the phenomenon where photons are absorbed in a medium and part of the absorbed energy is reemitted as photons. Broadly speaking, there are two categories of photoluminescent emission, fluorescence and phosphorescence. Each of these can be modeled in OpticStudio using the photoluminescence bulk scattering model available in non-sequential mode.
