Er~(3+)离子对Er~(3+)/Tm~(3+)共掺碲酸盐玻璃1.85μm波段光谱特性的影响
|
摘要
采用高温熔融淬火技术制备了1.0 mol%Tm~(3+)离子和x mol%Er~(3+)离子(x=0,0.5,1.0和1.5 mol%)掺杂的系列碲酸盐玻璃,通过测量玻璃样品的差热扫描曲线(DSC)、X射线衍射(XRD)图和荧光光谱,对不同Er~(3+)浓度下的玻璃物理性能和Tm~(3+)离子荧光特性进行了研究。DSC结果显示,研制的稀土掺杂碲酸盐玻璃具有优异的热稳定性能,玻璃样品的析晶温度与转变温度之差大于130℃,而XRD图则证实了研制的玻璃样品具有非晶结构特征。在808 nm泵浦激励下,随着Er~(3+)离子的引入,Tm~(3+)离子~3F_4→~3H_6能级间跃迁产生的1.85μm波段荧光显著增强。当Er~(3+)离子掺杂浓度为1.0 mol%时,荧光强度提高了约76%,荧光强度的显著增强归因于Er~(3+)离子和Tm~(3+)离子之间的能量传递。然而,随着Er~(3+)离子掺杂浓度的继续增加,1.85μm波段荧光呈现出衰减现象,这归结于Er~(3+)离子浓度的淬灭效应。研究表明,具有合适浓度Er~(3+)/Tm~(3+)共掺碲酸盐玻璃是一种应用于1.85μm波段固体激光器和光纤放大器的理想基质材料。
Er~(3+)/Tm~(3+) codoped tellurite glasses with fixed amount of Tm~(3+)(1.0 mol%) and variable amounts of Er~(3+)(0-1.5 mol%) were prepared by melt-quenching technique and investigated by the differential scanning calorimeter(DSC),X-ray diffraction(XRD) and fluorescence spectra measurements.The DSC results reveal that the prepared glass samples possess good thermal stability with ΔT.(the difference between the glass crystallization onset temperature and transition temperature) larger than 130 ℃ while the XRD patterns confirm the amorphous structural nature of glass system.Under the excitation of 808 nm laser diode(LD),the 1.85 μm band fluorescence of Tm~(3+):~3F_4→~3H_6 transition increases significantly with the introduction of Er~(3+),and an improvement by about 76% of fluorescence intensity was observed in the glass sample with 1.0 mol% amount of Er~(3+),which is attributed to the energy transfers between Er~(3+) and Tm~(3+) ions.However,with the further increase of Er~(3+) concentration,a fluorescence decaying phenomenon,mainly resulting from the concentration quenching effect of Er~(3+),occurred in the glass sample.The above results indicate that the prepared tellurite glass with appropriate codoped amounts of Er~(3+)/Tm~(3+) ions is a promising host material applied for 1.85 μm solid-state lasers and amplifiers.
