Source: Wikipedia Understanding Photoluminescence Understanding Photoluminescence Photoluminescence is a fascinating phenomenon where light is emitted by a material after it absorbs photons from an external light source. This process encompasses both fluorescence and phosphorescence, distinguished by the duration over which light emission occurs following irradiation. While the emitted light is often visible, it can also
