Abstract: The photoluminescence properties of inorganic borate host material BaB<sub>8</sub>O<sub>13</sub> doped with Eu<sup>2+</sup> have been studied. The material BaB<sub>8</sub>O<sub>13</sub>:Eu<sup>2+</sup> was prepared by a novel technique which is a slight variation of solution combustion synthesis. The synthesis is based on the exothermic reaction between the fuel (urea) and oxidizer (ammonium nitrate). The structure of the prepared sample was confirmed by powder XRD technique and photoluminescence properties were investigated. Under UV excitation (254 nm), BaB<sub>8</sub>O<sub>13</sub>: Eu<sup>2+</sup> shows intense broad emission band peak at 408 nm. The effect of concentration of Eu<sup>2+</sup> ions on the PL intensity has also been investigated. It has been observed that the powder sample exhibits highest PL emission intensity for Eu<sup>2+</sup> concentration of about 0.03 moles.
