Abstract
In this paper, we report on spectroscopic studies of Cr3+ / Ni2+ codoped transparent glass ceramics containing Β -Ga 2 O3 nanocrystals. Energy transfer between Cr3+ and Ni2+ in the Cr3+ / Ni2+ codoped glass ceramics has been investigated by steady state emission spectra, time-resolved emission spectra, and excitation spectra. The nonradiative energy transfer has been confirmed from the decrease in the Cr3+ fluorescence lifetime after Ni2+ codoping. The energy transfer efficiency is estimated and the energy transfer mechanism is discussed.
