A new Al₂O₃:C,Cu,P phosphor is developed by the combustion synthesis technique which exhibit sentirely different OSL properties as compared to that of the commercial alumina. Nothermoluminescence (TL) is observed in this phosphor which also differentiates the present phosphor from the commercially available Al₂O₃:C. (Landauer).The phosphor shows good optically stimulated luminescence (OSL) sensitivity for ionizing radiation with a fast OSL decay as compared to the commercial Al₂O₃:C. The phosphor heated in air followed by heating under the reactive atmosphere exhibits maximum sensitivity amongst several other phosphors. On the basis of area integration method; integrated over initial 3s,the sensitivity of this phosphoris about 67% of that of commercial Al₂O₃:C.
