Visible photoluminescence in K1-xLixTaO3 was found to have similar spectral features but a large increase of emission yield with respect to KTaO3. 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.

Abstract

Visible photoluminescence in K1-xLixTaO3 was found to have similar spectral features but a large increase of emission yield with respect to KTaO3. 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.

Applied Physics/Condensed Matter/Materials Science encompasses the resources of three related disciplines: Applied Physics, Condensed Matter Physics, and Materials Science. The applied physics resources are concerned with the applications of topics in condensed matter as well as optics, vacuum science, lasers, electronics, cryogenics, magnets and magnetism, acoustical physics and mechanics. The condensed matter physics resources are concerned with the study of the structure and the thermal, mechanical, electrical, magnetic and optical properties of condensed matter. They include superconductivity, surfaces, interfaces, thin films, dielectrics, ferroelectrics and semiconductors. The materials science resources are concerned with the physics and chemistry of materials and include ceramics, composites, alloys, metals and metallurgy, nanotechnology, nuclear materials, adhesion and adhesives. Resources dealing with polymeric materials are listed in the Organic Chemistry/Polymer Science category.
