Abstract

The photoluminescence property of pure and MgO co-doped near stoichiometric LiNbO ₃ :Cr crystals has been investigated. It has been found that the presence of low Mg ion content in the crystals induces the coexistence of two types of Cr ³⁺ sites; Cr ³⁺ ion substituting Li ⁺ and Nb ⁵⁺ sites. In MgO co-doped samples, four narrow emission bands have been found and three of them are correlated with the broad absorption bands associated to the Cr ³ + ions located in Nb ⁵⁺ site ([Cr] _Nb centres). The observation of the zero-phonon line at 13 540 cm ^-1 only in pure LiNbO ₃ :Cr crystals of near stoichiometric composition suggests it could be used as a probe to monitor the composition of LiNbO ₃ crystals.
