Photo-luminescent material is defined

After the light-emitting material inside is in some way to absorb energy in the form of optical radiation outside the thermal radiation emitted from the excess energy in the process. Excitation light emitting material generated phenomenon, known as photochromic masterbatch. Photoluminescent material is a major application area lighting, including low-pressure mercury lamp, high pressure mercury lamp, fluorescent color, three-color lights and UV lights. Another important field of application of its plasma display.
