Abstract

We investigated the photoluminescence properties of near-stoichiometric LiNbO₃ crystals doped with Tb only and double doped with Tb and Fe. Excitation spectra for the emission from the ⁵D₄ state in both crystals have been studied in the range 200-500 nm. We observed two broad ultraviolet absorption bands and discussed their relations to Tb ions. Temperature dependence of the ⁵D₄ emission intensity and lifetime showed strong quenching below room temperature.
