Photoluminescence Spectroscopic Study of BaMgAl10O17:Eu Phosphor Coated with CaF2 via a Sol-Gel Process

CaF2 coatings on the surface of BaMgAl10O17:Eu (BAM) were prepared by a sol-gel process, and the optical properties and antithermal degradation properties were analyzed by photoluminescence spectra recorded under 254 nm and 147 nm excitation. The results indicate that BAM particles were successfully...
