摘要：
The optical absorption and luminescence of Cr3+ ions in ZnO doped LiNbO3:Cr3+ crystals have been studied. It has been found that ZnO produces the same effect as that observed in MgO co-doped samples: A strong reduction in the Cr3+ concentration together with a shift in the 4A2-->4T1 vibronic transition to lower energy. As in the case of MgO co-doped samples a new Cr3+ centre is formed in ZnO co-doped samples.
