Photo and cathodoluminescence of commercial YAG:Ce based phosphors in UV region

Abstract

The luminescence spectral kinetic characteristics in UV and visible spectral regions of a group of commercial YAG:Ce based phosphors are investigated under excitation by UV radiation in the spectral range of 300–210 nm (photoluminescence, PL) and high-energy electrons (0.25 MeV, pulse cathodoluminescence, PCL). It was established that UV luminescence appears in all phosphors, whose spectrum consists of bands in the region of 312, 320, 380 nm and 530–565 nm. The kinetics of the PCL UV luminescence decay in all phosphors shows at least one, two components in different phosphors but is differ from kinetics of luminescence in the visible region. The possible structure of luminescence centers responsible for UV luminescence is discussed.
