| 英文摘要 | Glasses with compositions of (95.8-x) SiO2-4Al(2)O(3)-xP(2)O(5)-0.2Nd(2)O(3) (in mol%, x = 0-10) were prepared. Structural variation caused by P5+ was investigated by Judd-Ofelt parameters and Raman spectra. Results reveal that Nd3+ preferentially coordinates to P=O sites at molar ratio of P5+/Al3+ > 1 and thus it leads to a sudden change in fluorescence effective linewidth, stimulated emission cross section, fluorescence lifetime and non-radiative transition rate of Nd3+ ions. The fluorescence lifetime changes in the range of 315-379 mu s. The emission cross section changes in the range of 139-1.79 x 10(-20) cm(2). With the increase of P5+/Al3+ ratio, the fluorescence effective linewidth varies from 45.77 to 37.03 nm. The shortest fluorescence lifetime was observed at molar ratio of P5+/Al3+ = 1. The maximum non-radiative transition rate of 1694/s occurred at molar ratio of P5+/Al3+ = 1.25. The highest emission cross section of 1.79 x 10(-20) cm(2) was obtained at the highest P5+/Al3+ molar ratio. Furthermore, structure-property relationship in these glasses was discussed through Judd-Ofelt parameters and luminescent behaviors. (C) 2015 Elsevier B.V. All rights reserved. |
