<p><P>PROBLEM TO BE SOLVED: To provide a scintillator with sufficiently great fluorescence output and sufficiently short fluorescence decaying time. <P>SOLUTION: The scintillator whose matrix consists of rare earth metal silicate crystal is provided. In this scintillator, the rare earth element is selected from Sc, Y, La, Gd and Lu. This scintillator contains Ti and Ce as the emission center elements with the molar ratio Ti/Ce being preferably (1:10,000) to (1:10). <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
