Abstract
In this paper we have reported the luminescence characterizations of rare earths Ce and Eu activated MBPO5 (M=Sr, Ca) phosphors synthesized by modified solid state reaction and studied for photoluminescence (PL) studies. The incorporation of Ce and Eu in 3+ oxidation state was ascertained from PL studies. The spectral characteristics have revealed that the excitation spectra of Eu2+ activated SrBPO5 phosphor shows the strong broad peak observed at 354nm (monitored at 422nm) near UV region and is favorable to solid-state lighting excitation. The orange–red (589 and 591nm) emission in Eu3+ activated CaBPO5 is due to 5D0–7F1 transition of Eu3+ and this is permitted only in cases of Cs, Cn, and Cnv symmetries observed at Eu3+ sites. All these are the features of the f↔f transition of the trivalent europium ion. PL properties of Ce3+ activated MBPO5 (M=Sr, Ca) revealed the broad band emission at 375nm.
