Study of Thermoluminescence and Optically Stimulated Luminescence Properties of Synthesised CaBO Nanoparticles Doped with Copper.

CaBO nanorods doped with different concentrations of Cu were prepared by using co-precipitation method. The recorded Thermoluminescence (TL) and Optically stimulated luminescence (OSL) of CaBO:Cu samples for different concentrations of Cu irradiated with 6 Gy of X-Ray shows that 0.05 at.wt% of Cu concentrations have higher sensitivity. The TL and OSL kinetic parameters of glow curves were evaluated using "tgcd" and conventional fitting methods. The TL glow curve of the CaBO:Cu have three individual glow peaks with maximum peak temperatures at 404.50, 453.04 and 484.02 K respectively. The OSL glow curves of the CaBO:Cu nanoparticles follow non-first order kinetics which can be fitted with the sum of two first order decay curves.
