Abstract

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.
