The effect of Ti co-doping in BaAl 2 O 4 :Eu 2+ phosphor material on crystalline quality, morphology and photoluminescence (PL) characteristics was investigated. The co-doped green phosphor compositions (BaAl 2 O 4 :Eu 2+ , Ti 3+ ) with varying concentrations of Ti were prepared by solid-state synthesis method. These compositions were characterized for their phase, morphology and crystallinity by powder X-ray diffraction, SEM and TEM techniques. The photoluminescence properties were investigated measuring PL and decay time. Broad band UV excited luminescence was observed for BaAl 2 O 4 :Eu 2+ , Ti 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.
