    Abstract

    Scintillation and optical properties of cerium (Ce)-doped 20Al(PO3)3-80LiF (APLF) glass samples prepared by melt quenching are investigated. The properties of these samples are dependent on the doping concentration, and quenching with high Ce concentration is not observed. A high quantum efficiency of 95% is achieved with 3 mol% Ce and with a decay time of around 40 ns from the allowed 5d-4f transition at 350 nm. This quantum efficiency is high compared to other Ce-doped materials such as Ce:LiCaAlF6 laser crystals. Ce-doped APLF glass can then be used as illuminators, wavelength converters, and scintillators in the ultraviolet region.
