Abstract
BaLiF3, KY3F10, and Na0.4Y0.6F2.2 crystals activated with rare-earth i ons are studied. The partition coefficients of some rare earths are ev aluated, and various grown-in structural defects are identified. The a ssignment of the cathodoluminescence spectra for KY3F10 and Na0.4Y0.6F 2.2 is presented. The luminescence buildup time in rare-earth-activate d Na0.4Y0.6F2.2 is found to be as long as a few minutes. The time vari ation of cathodoluminescence intensity is measured at various electron -beam currents.
