Trap depth and Dy3+ luminescence in BaAl2Si2O8 phosphor

In this article we have reported Dy3+ luminescence in BaAl2Si2O8 phosphors by combustion synthesis at 600 °C. Phosphor shows emission bands at 484 nm and 577 nm, keeping excitation constant at 367 nm ranging from 300 to 400 nm. Till date there is no report on BaAl2Si2O8:Dy3+ phosphors. Thermoluminescent characterization was carried out to study trap depth in BaAl2Si2O8:Dy3+ phosphor. Phosphor was further characterized by XRD for the confirmation of phase purity. Therefore observed broad blue and yellow bands in Dy3+ ions show that phosphor may be applicable for white-LEDs.
