摘要：

The origins of two decay constants in the scintillation decay of cerium-doped gadolinium oxyorthosilicate (Gd2(SiO4)O:Ce) are investigated using UV light. We find that build-ups and long decay components observed with gamma-ray excitation are due to non-radiative energy transfer from Gd to Ce. The transfer rate from Gd to Ce increases as the Ce concentration increases. The gamma-ray excited decay curves of GSO are composed of prompt Ce emission and delayed Ce emission (transfer of energy through Gd), as observed by UV excitation.
