Optical absorption and photoluminescence properties of Eu3+-doped ZnF2-PbO-TeO2 glasses

摘要

Several physical, optical absorption and photoluminescence properties of Eu3+-doped ZnF2-PbO-TeO2 glasses have been studied. From the measured intensities of various absorption bands of these glasses the Judd-Ofelt parameters Omega(2), Omega(4) and Omega(6) have been computed. The Judd-Ofelt theory has been applied to characterize the photoluminescence spectra of these glasses. From this theory, various radiative properties, such as transition probability, A, branching ratio, beta(r) and emission cross-section, sigma(P)(E), for various emission levels of these glasses, have been determined and reported.
