Green phosphor BaAl 2 O 4 :Eu 2+ , Cr 3+ 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 BaAl 2 O 4 :Eu 2+ , Cr 3+ in the green region (λ max =500nm) due to transitions from 4f 6 5d 1 to the 4f 7 configuration of the Eu 2+ ion. The effect of Cr doping on crystalline quality, morphology and photoluminescence characteristics of prepared compositions was investigated.
