| 英文摘要 | Crystal structure of Cs2LiY0.95Cl6:5%Ce crystal (CYLC): grown by vertical Bridgement method from polycrystal raw materials was measured by X-ray diffraction (XRD) and was proved to have elpasolite structure. The detected structure of Cs2LiYCl6:Ce crystal was agreed well with theoretical structure. Six optical absorption bands which are suggested to originate from the transition of electron from 4f to 5d(1 similar to 5) of Ce ions and self-trapped excition (STE), can be identified in the absorption spectra of the CLYC:Ce crystal. X-ray and ultraviolet excited luminescence spectra of Cs2LiY0.95Cl6:5%Ce crystal present an emission band from 350 nm to 450 nm corresponding to 5d-4f transitions of Ce3+ ions. The peaks locating at 300 nm and 321 nm can be ascribed to core to valence luminescence and STE luminescence. Under the excitation of gamma-rays from Cs-137, Cs2LiY0.95Cl6:5%Ce crystal presents energy resolution of 8.1%, and scintillation decay time of 58 ns and 580 ns. All of these properties show that Cs2LiYCl6:Ce crystal is a promising scintillator for neutron and gamma detection applications. |
