Paper Title - Luminescence Studies in BaWO4: Eu Phosphors
BaWO4 phosphor is synthesized by solid state diffusion method. Thermoluminescence (TL), lyoluminescence
(LL), mechanoluminescence (ML) and photoluminescence (PL) of the BaWO4 phosphor material is studied. In TL glow
curve a single peak is observed around 160 0C. A single peak is also observed in LL glow curve. Intense ML is observed
when the irradiated BaWO4:Eu phosphor is deformed by dropping a load onto the sample, from certain height. PL emission
curves exhibit a single peak around 480 nm, which are due to Eu2+ and Eu3+ ions respectively. The spectroscopic analysis
shows that TL and LL are due to Eu2+ ions, but in ML, role of both the ions are important.
