Optical absorption spectra of the xCeSZP glasses.
PL-PLE spectra of the 0.05CeSZP glass at different excitation energies.
Contour plots of PL intensity of the xCeSZP glasses with different amounts of Ce concentration. (a) 0, (b) 0.01, (c) 0.05, (d) 0.1, (e) 0.5, and (f) 1.0 mol. %. Linear scale is used for the intensity axis.
Peak photon energies of xCeSZP glasses as a function of CeO2 amount.
Emission decay curves at 3.1 eV (Sn2+ emission) of the xCeSZP glasses. The decay curves were measured at r.t. using a 280 nm (4.43 eV) LED.
(a) RL spectra of the xCeSZP glasses. (b) Emission spectra of the 0.05CeSZP glass with different excitation energies.
RL spectra of the ySnO-1CeOα-59ZnO-40P2O5 glasses (y = 0: closed squares, y = 1.0: open circles, and y = 3.5 solid line.) Emission intensity of 3.5SnO-1CeOα-59ZnO-40P2O5 glass is displayed as one-twentieth for comparison.
