| Abstract: | As a novel scintillation material, the use of Ce-doped Gd_{2}Si_{2}O_{7} was investigated. In fact, (Gd_{0.9}Ce_{0.1})_{2}Si_{2}O_{7} powder showed about five-times greater light output than Gd_{2}SiO_{5} (GSO) powder samples for alpha-particles from ^{241}Am. Furthermore, a fast decay constant of 59 ns was obtained for alpha-particles from ^{241}Am. Relations between the Ce-concentration, crystal structure and luminescence characteristics were also elucidated. Results of these studies show that heavy Ce-doping alters the Gd_{2}Si_{2}O_{7} crystal structure and that the luminescence intensity is dependent not on Ce-concentration but on the triclinic structure formed by heavy Ce-doping. |
