摘要：

The up-conmverted hot luminescence technique was utilized to obtain information on the nonradiative relaxation in Ni2+:MgO. The experiment shows the presence of an electronic bottleneck associated with the T-3(1)(t(4)e(4)) electronic state which was determined to be at 2.973+/-0.003 eV (23978+/-25 cm(-1)). The spectral profiles indicate that the 395+/-15 cm(-1) phonon mode is involved in the nonradiative relaxation of the impurity Ni2+ ions. (C) 1995 American Institute of Physics.
