文摘

Green, orange emissions of Sm3+−Ho3+ in ZnO-SrO-P2O5: Pb3O4 glasses investigated. 8.0 mol% of Pb3O4 is the optimal concentration for getting intense G and R lines. Increased efficiency of G and R lines is attributed to the decreasing covalent character. EPR, OA spectra of RE free glasses indicated that lead ions do exist in Pb3+ state.
