摘要

For studied LiAlSi2O6 spodumene crystals, afterglow effect was observed and explained. The luminescence spectra under femtosecond excitation have been presented for this crystal for the first time. The emission bands of point defects in blue, besides those of Mn2+ in orange, have been measured. We demonstrate that emission from defects causes sustaining of emission of Mn2+, and thus, the afterglow phenomenon occurs. The various quantitative ratio of Mn(2+ )to defects causes the changes in afterglow phenomenon.
