| 摘 要： | 测量了氟锆酸盐玻璃中Dy3+离子的吸收光谱和荧光光谱,得到了Dy3+离子的J-O参量Ωt,Ω2=3.29×10 20cm2,Ω4=1.56×10 20cm2,Ω6=2.48×10 20cm2.计算了氟锆酸盐玻璃中Dy3+离子的发射特性,Dy3+离子1.3μm发射的6F11/2(6H9/2)→6H15/2跃迁的发射截面σe=0.62×10-20cm2.研究了Dy3+离子浓度对其荧光强度的影响,当Dy3+离子掺杂浓度(摩尔分数)超过1.5%时,发生了浓度淬灭效应.

| Abstract: | Optical absorption and emission bands was measured and assigned to transitions between the energy levels of Dy3+ ions. Optical characteristics of Dy3+-doped glasses in the system of ZrF4-based fluorides were investigated. Intensity parameters Ωt (t=2, 4, 6) were obtained using the Judd-Ofelt theory with a reasonable agreement between theory and experiment. The emission cross section of 6F11/2 + 6H9/2 →6H15/2 transition of 1.3μm emission was calculated. The effect of the Dy3+ concentration on the emission intensities has been discussed. Concentration quenching was observed in the sample containing 1.5% (mole fraction). |
