    AnnotationVisible photoluminescence in K_1-xLi_xTaO_3 was found to have similar spectral features but a large increase of emission yield with respect to KTaO_3. Studying the temperature dependence of the phenomena and its correlation with photoconductivity, we found direct support for a process in which the emission is due to pair recombination of trapped electron and hole centers, Ta4+ and O-, intrinsic to the matrix.
