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.
采用共沉淀法制备了掺杂不同浓度铜的CaBO纳米棒。对不同铜浓度的CaBO:Cu样品在6 Gy X射线辐照下记录的热释光（TL）和光激发发光（OSL）表明，0.05 at.wt%的铜浓度具有更高的灵敏度。使用“tgcd”和传统拟合方法评估了发光曲线的TL和OSL动力学参数。CaBO:Cu的TL发光曲线有三个单独的发光峰，最大峰温分别为404.50、453.04和484.02 K。CaBO:Cu纳米颗粒的OSL发光曲线遵循非一级动力学，可由两条一级衰减曲线的总和拟合。
