Because the energy of vacuum ultraviolet (VUV) photons emitted by xenon plasma discharge is more than twice that of visible photons, quantum cutting appears to be a promising process in rare-earth doped materials in order to obtain efficient phosphors for mercury free lighting devices as well as for plasma display panels. With an aim of application, it is important to take into account the emitting...
In the framework of research of efficient phosphors quantum cutting (QC) associated with strong absorption is an attractive process. Because of their wide band gap and the position of their f→d transitions, fluorides YF3:Tb3+ and YF3:Dy3+, Tb3+ are studied in the UV and VUV spectral regions. Emission and excitation spectra, fluorescence decay-times are presented. Theoretical prediction of QC has not...
