Photoluminescence Spectroscopic Study of BaMgAl 10 O 17 :Eu Phosphor Coated with CaF 2 via a Sol-Gel Process

CaF 2 coatings on the surface of BaMgAl 10 O 17 :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 success...

Description
Summary:CaF 2 coatings on the surface of BaMgAl 10 O 17 :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 coated with CaF 2 and CaF 2 coatings show an interesting property to enhance the blue emission intensity of BAM. The optimum antithermal degradation properties were obtained at the weight ratio 0.4 wt% under 254 nm excitation and 0.3 wt% under 147 nm excitation, respectively.
