Combustion Synthesis and Thermo Luminescence in γ-Irradiated Borate phosphors Activated with Terbium(III)

The crystalline sample of NaSrBO3 and NaSr4(BO3)(3) was successfully synthesized by a combustion method and for use of these material in a radiat on dosimetry. Its thermo luminescence characteristics has also been studied. Formation of the compound was confirmed by studying the X-ray diffraction pattern. The therm luminescence glow curve of the NaSrBO3 doped with 0.01 mol of Tb has a simple structure with a single peak at 150 degrees C, where as NaSr4(BO3)(3) doped with 0.01 mol of Tb give a weak peak at 187 degrees C and prominent peak at 314 degrees C. Thermo luminescence sensitivity of the both the phosphors for gamma-rays is found as sensitive as that of LiF : Mg, Cu, P. Kinetic parameten, and dose response of these materials also reported.
