英文摘要:
Nd3+-doped P2O5-K2O-Al2O3-BaO-PbO phosphate glasses with various PbO/BaO ratios were synthesized using the melt quenching technique. Raman, absorption, and emission spectra were measured to investigate the effects of PbO/BaO ratios on the structures and spectroscopic properties of the glasses. The emission cross-sections of the Nd3+-doped phosphate glasses were calculated using the Judd-Ofelt theory, and were found to increase from 4.37 x 10(-20) to 4.50 x 10(-20) cm(2) as the PbO/BaO ratio increased. In addition, thermo-optical properties were measured using an interferometric technique. The thermooptical coefficients, which were -1.49 x 10(-6), -1.65 x 10(-6), and -1.64 x 10(-6) K-1, respectively, were all largely negative values. The thermal expansion coefficients of the three glass samples varied within a small range. The results showed that increasing the PbO/BaO ratio of phosphate glasses can improve the laser properties while maintaining their good thermo-optical properties. (C) 2017 Elsevier B.V.
