Strontium silicate (Sr 2 SiO 4 ) nano phosphor was synthesized by low temperature solution combustion technique using citric acid and glycine fuels. The obtained products were characterized by Powder X-ray Diffraction (PXRD), Fourier Transform Infrared Spectroscopy (FTIR) and PXRD confirms the formation of single phase monoclinic and orthorhombic Sr 2 SiO 4 nano phosphor. Thermoluminescence (TL) of Sr 2 SiO 4 nano phosphor exposed to 60 Co gamma irradiation in the dose range 1- 6Gy has been studied. A single well resolved glow peak was obtained at 175°C for citric acid and at 180°C for glycine fuel respectively. The kinetic order (b), activation energy (E) and frequency factor (S) are calculated by Chen's modified peak shape method.These results show the nanocrystalline phosphor of Sr 2 SiO 4 is suitable for radiation dosimetry.
