Abstract
Green phosphor BaAl2O4:Eu2+, Cr3+ with varying concentrations of Cr codoping were prepared by solid-state synthesis method. The synthesized compositions were characterized for their phase, morphology and crystallinity by powder X-ray diffraction, SEM and TEM techniques. Photoluminescence properties were investigated measuring PL and decay time. Broad band UV excited luminescence was observed for BaAl2O4:Eu2+, Cr3+ in the green region (λmax = 500 nm) due to transitions from 4f6 5d1 to the 4f7 configuration of the Eu2+ ion. The effect of Cr doping on crystalline quality, morphology and photoluminescence characteristics of prepared compositions was investigated.
