Synthesis and optical studies of novel Eu2+ and Ce3+ doped BaMg8Al18Si18O72 phosphors

Novel Eu2+ and Ce3+ activated BaMg8Al18Si18O72 phosphors was prepared by combustion method and their PL characteristics were investigated. The result shows that all samples can be excited efficiently by near UV excitation under 334 nm and 316 nm. The emission was observed for BaMg8Al18Si18O72:Eu2+ phosphor at 437 nm corresponding to d → f transition, under 334 nm broad-band excitation, whereas BaMg8Al18Si18O72:Ce3+ phosphor shows emission band at 376 nm under 316 nm excitation. Phase purity of the phosphor was checked with the help of XRD pattern. SEM analysis shows the external morphology of the combustion synthesized phosphor.
