研究了混合形成体效应对掺铒碲酸盐玻璃热力学稳定性、1.53 μm发光特性和上转换发光强度的影响.通过拉曼光谱测试,分析了WO3,Nb2O5,GeO2等氧化物对Er3+离子配位场结构,以及对发光谱的非均匀展宽机理的作用.结果表明,通过掺杂适当声子能量的网络形成体氧化物,不但可获得热力学稳定性较好的玻璃,还可有效降低Er3+离子4I11/2能级的寿命,在抑制Er3+离子在可见光波段的上转换发光的同时不致劣化其在1.53 μm的发光特性.本文制得的碲酸盐玻璃具有较大的受激发射截面((9.64—10.96)×10-21cm2)和荧光半高宽(FWHM)(50—67 nm),热力学稳定性良好,是一种理想的掺Er3+宽带有源光纤用基质玻璃.The influence of mixed former effect on the thermal stability,1.53 μm emission and the infrared to visible upconversion emission of the Er3+-doped tellurite glasses are investigated.The inhomogeneous broadening of emission spectrum of Er3+ ion with several network formers (WO3,Nb2O5 and GeO2)is discussed by Raman spectra.The results indicate that for Er3+-doped tellurite glass,besides improving the thermal stability of glasses,introducing the network former with appropriate phonon energy is helpful for the improvement of 1.53 μm emission via decreasing the lifetime of Er3+ ∶4 I11/2 level,and lowering the upconversion luminescence in visible wavelength.The present glasses exhibit a large emission cross section ((9.64—10.96)×10-21 cm2)and broad full width at half maximum (FWHM)(50—67 nm),which make them promising host materials for broadband Er3+-doped fiber.
