采用常规熔淬技术制备了具有良好热稳定性的Nd3+、Tm3+和Ho3+掺杂碲酸盐玻璃。研究了808 nm激光二极管（LD）激发下的近红外发光特性。在1200 ~ 2200 nm的光谱范围内，掺有0.015 mol% Nd2O3、0.32 mol% tm2o3和0.045 mol% Ho2O3的Nd3+/Tm3+/Ho3+三掺碲酸盐玻璃同时观察到1300 ~ 1600 nm和1600 ~ 2200 nm两个超宽带发光带。这两个发光带的半峰全宽度（FWHM）分别达到203 nm和374 nm。制备的碲酸盐玻璃的玻璃化温度为379℃左右，玻璃化差为136℃左右。研究了其结构性质、光谱性质和荧光衰减行为，以更好地理解其发光现象。同时获得的两个超宽带发光带的结果表明，Nd3+/Tm3+/Ho3+三掺杂碲酸盐玻璃是一种很有前途的多功能应用材料。
Nd3+, Tm3+and Ho3+doped tellurite glasses with good thermal stability were prepared by conventional melt-quenching technique. The near-infrared luminescence properties were investigated under the excitation of 808 nm laser diode (LD). In the studied spectral range of 1200–2200 nm, two ultra-broadband luminescence bands of 1300–1600 nm and 1600–2200 nm were observed simultaneously in Nd3+/Tm3+/Ho3+tri-doped tellurite glass with amounts of 0.015 mol% Nd2O3, 0.32 mol% Tm2O3and 0.045 mol% Ho2O3, which have not been reported yet for this tri-doped combination. The full width at half maximum (FWHM) of this two luminescence bands were up to 203 and 374 nm respectively. In addition, the glass transition temperatureTgand the difference ΔTof the prepared tellurite glass were about 379°C and 136°C respectively. The structural property, spectroscopic property and fluorescence decay behavior were investigated to better understand the luminescence phenomena. The result of two ultra-broadband luminescence bands obtained at the same time in present work indicates that Nd3+/Tm3+/Ho3+tri-doped tellurite glass is a promising multifunctional application material.
