摘要
An approximately microscopic model is developed for the Cr3+-6O(2-) cluster and applied to study the optical data and electron paramagnetic resonance (EPR) g-factors and the zero-held splitting D-value in LiNbO3:Cr3+. Analysis of the optical and EPR data indicate that Cr3+ ions substitute at Nb sites and Nb-vacancy (Li) sites simultaneously. The results are in good agreement with the experimental findings. This means that the optical and EPR data and the substitution site of Cr3+ ions in LiNbO3 can be interpreted uniformly.
