The narrow UVB emitting alkali metal aluminate phosphor doped with Gd3+ has been prepared by a solution combustion synthesis technique. The formation of the sample was confirmed by powder X-ray diffraction technique. The spectroscopic property of prepared material was studied at room temperature. The phosphor NaAlO2 shows emission in narrow band UVB under the excitation of 275 nm. Stokes shift of sample also been calculated using corresponding excitation and emission wavelengths. Because of narrowband ultraviolet (UV) emission the phosphor could be effective choice for UV phototherapy lamps
