Yb3+敏化宽波带掺Er3+氟磷酸盐玻璃的发光性质及Judd-Ofelt理论研究
Luminance Properties and Judd-Ofelt Theory Study of Yb3+ Sensitization Wideband Er3+ Doped Fluorphosphate Glass
摘要
Abstract
A new Er3+Yb3+ -codoped fluorphosphate glass was prepared by high temperature melting. Its density, absorption spectra, and fluorescence spectra were measured and investigated. The effect of Er3* and Yb3+ concentrations on the spectroscopic properties of the glass sample are discussed. A Judd-Ofelt theory analysis on the absorption spectra was performed. The oscillator strengths were Ω1 (t=2, 4, 6 ), Ω2= 4.36X10-20 cm2, a=1.35x10-20 cm2, and Ω6=0.79×10 cm2. The lifetime (Tm) of the 4/13/2 level for the Er3+ ions was 8.26 ms and the full width at half maximum (FWHM) of the main emission peak was 68 nm at 1.53 pm. The large stimulated emission cross-section (σe=8.5x10-21 cm2) of the Er3* was calculated using McCumber theory. The spectroscopic properties of the Er3* ion were compared among different glasses. The FWHM and ct. Of Er3+TYb3+codoped fluorphosphate glass were found to be larger than those of other glass hosts, which indicates that this glass may be a potentially useful candidate material host for a high-gain erbium-doped fiber amplifier.关键词
