Abstract

The crystallographic axis dependence of the absorption and photoluminescence spectra of Ti:BeAl2O4 is rationalized by assuming that the (3d)1 electron energy levels are split by the cubic and orthorhombic fields present at the Al site in chrysoberyl. The temperature dependence of the luminescence lifetime and integrated intensity indicates that the lifetime shortening that accompanies temperature increase is due to a nonradiative transition with an activation energy estimated to be 1770 cm−1.
