摘要：

The thermally and optically stimulated luminescence (TSL and OSL) properties of Cu-doped CaF2 ceramics synthesized by spark plasma sintering (SPS), as well as their scintillation and photoluminescence (PL) properties, were investigated. The PL and scintillation spectra showed emission peaks at 390 and 490 nm, which were ascribed to Cu+ ions and Cu clusters, respectively, judging from the PL decay time constants. After X-ray irradiation, TSL and OSL were observed upon heating at 182 degrees C and irradiating light of 620 nm, respectively. The dominant luminescence centers in the TSL and OSL processes were considered to be Cu clusters. The 0.1% Cu-doped CaF2 sample had a linear TSL response in the dose range from 0.01 to 1000 mGy.
