High temperature optical spectroscopy investigations on Zr0.78Y0.18Sm0.04O1.89 and Zr0.78Y0.18Ho0.04O1.89 single crystals
Abstract
Results are reported from a temperature dependent optical study of the title compounds performed at temperatures up to 1323 K. Absorption maxima and integrated absorption of rare earth f–f transitions exhibit a considerable temperature dependence, which is quantitatively described in the framework of the optical high temperature
