| Abstract |
| Nanocrystalline wollastonite (-CaSiO3) phosphor powder has been synthesized by low temperature combustion method and characterized by powder XRD (X-ray diffraction). The structural morphology and the particle size have been analyzed by SEM (scanning electron microscopy) and TEM (transmission electron microscopy) respectively. The powder has been subjected to -irradiation and the resulted thermoluminescence (TL) behaviour has been investigated. The TL glow curves reveal that the TL intensity increases with the radiation dose, a property desired by a TL dosimeter. The trapping parameters like activation energy (E) and order of kinetics (b) were estimated by deconvolution method using peak shape of 60 Gy glow curve and the results are discussed. |
