Abstract
Visible photoluminescence in K1-xLixTaO3 was found to have similar spectral
features but a large increase of emission yield with respect to KTaO3. Stu
dying the temperature dependence of the phenomena and its correlation with
photoconductivity, we found direct support for a process in which the emiss
ion is due to pair recombination of trapped electron and hole centers, Ta4 and O-, intrinsic to the matrix.
