Synthesis and TL/OSL properties of CaSiO3:Ce biomaterial

The polycrystalline CaSiO3:xCe (x=0.001, 0.002, 0.005) biomaterials were prepared by using solid state diffusion (SSD) method. The structure of CaSiO3:Ce phosphor was confirmed by X-ray diffraction technique. Moreover, photoluminescence (PL), thermoluminescence (TL) and optically stimulated luminesc...

Description
Summary:The polycrystalline CaSiO3:xCe (x=0.001, 0.002, 0.005) biomaterials were prepared by using solid state diffusion (SSD) method. The structure of CaSiO3:Ce phosphor was confirmed by X-ray diffraction technique. Moreover, photoluminescence (PL), thermoluminescence (TL) and optically stimulated luminescence (OSL) properties were studied. The TL glow curves consist overlapping peaks in temperature range 40–450°C. The peak shape method was adopted for the calculation of the kinetic parameters such as activation energy, frequency factor and shape factor. The OSL sensitivity of CaSiO3:Ce phosphor was 2.8 time than that of OSL sensitivity of Al2O3:C (BARC) phosphor. The minimum detectable dose (MDD) was found to be 43.6μGy corresponding to 3σ background. •CaSiO3:Ce phosphors were synthesized via Solid state Method.•First time report TL/OSL properties of CaSiO3:Ce under beta irradiation.•OSL Sensitivity was about 2.8 time than that of commercially available α-Al2O3.•Dose response was linear nature in range 20–20,000mGy.•The Minimum detectable dose was found to be 43.6μGy corresponding to 3σ background.
