Progress in the spectroscopic and thermal studies of Er-doped oxysulfide crystal powders

Abstract : Gadolinium oxysulfide crystal is a wide-gap semiconductor material known as an excellent host for trivalent rare-earth ions. The present investigation explores the upconversion and thermal properties of Er3+-doped Gd2O2S crystal powders as well as their potentiality for anti-Stokes cooling. A detailed study of the wavelength and pumping power dependence of the spectroscopic properties and temperature field for samples of various erbium concentrations is presented. © 2016 SPIE.
