In this work we report the synthesis of CaWO4 pure and doped by various concentration of Eu3+ by solid state method. Crystallinity and formation of as-synthesized phosphors were confirmed by XRD technique. PL emission of the Eu3+ activated as-synthesized phosphors shows the strong red emission at 619 nm which corresponds to the characteristic transition 5D0 → 7F2 of Eu3+ ion at excitation wavelength 273 nm. TL glow curve of Eu3+ activated CaWO4 shows the two glow peaks was observed at 400K and 500K whereas undoped CaWO4 shows only single peak observed at low temperature (354K). Doping effect on TL glow curve was discussed. Glow curve of Eu3+ activated were fitted to five peaks which were analyzed and trap parameter were calculated by using Chens’ method, and the dose response curve shows the phosphor is fairly sensitivity to lower dose also. Thus reported phosphor can be applicable in LED and environmental dosimetry.
