Abstract

The emission intensity of Ni²⁺ at 1200 nm in transparent ZnO-Al₂O₃-SiO₂ glass ceramics containing ZnAl₂O₄ nanocrystals is improved approximately 8 times by Cr³⁺ codoping with 532 nm excitation. This enhanced emission could be attributed to an efficient energy transfer from Cr³⁺ to Ni ²⁺, which is confirmed by time-resolved emission spectra. The energy transfer efficiency is estimated to be 57% and the energy transfer mechanism is also discussed.
