A luminescent material emits light after its excitation by any source other than heat (e.g. UV radiation, electron beam, pressure, etc). In that context, we can distinguish fluorescent materials with lifetimes of the excited state ranging approximately between 10-9 and 10-3 s and materials with long persistent luminescence (also called phosphorescence) that have the propensity to emit light for several minutes or hours after cessation of the excitation. In both cases, we are interested in the characterization of the physical phenomenon, the determination of its origin and its adaptability to the target application. In a non-exhaustive manner, the materials synthesized at the laboratory are oxides, silicates, aluminosilicates or sulphides, in the form of micrometric powders or nanoparticles. Besides luminescence in the visible, we focus more and more on materials with emission in the infra-red domain.
