摘要: 利用气悬浮方法制备了Nd3+/Yb3+共掺La2O3-TiO2-ZrO2前驱体玻璃, 通过热处理获得了微晶玻璃。通过DTA对前驱体玻璃的热稳定性进行了研究。利用光致发光谱, TEM和EDS对微晶玻璃进行了表征分析, 并研究了热处理对上转换发光的影响。结果表明: 玻璃转变温度和析晶起始温度分别为799℃和880℃. 在980 nm激光激发下, 样品发射出中心位于497, 523, 545, 603和657 nm处的五条发光带。热处理后样品上转换发光强度提高, 经过880℃保温50 min热处理的微晶玻璃显示了最强的上转换发光, 在545 nm处的发光强度是前驱体玻璃的11倍, 这是由于在微晶玻璃基质中存在致密柱状晶和Nd3+离子在晶体中富集造成的。

Abstract: Nd3+/Yb3+ co-doped La2O3-TiO2-ZrO2 glass-ceramic samples were prepared by heat treatment of precursor glasses fabricated via aerodynamic levitation method. The thermal stability of the precursor glass was studied by DTA. The glass-ceramic samples were characterized by photoluminescence spectra, TEM and EDS. The effects of heat treatment on the upconversion luminescence were studied. The DTA curve shows that the glass transition temperature and the onset temperature of crystallization are 799℃ and 880℃, respectively. Five emission bands centered at 497, 523, 545, 603 and 657 nm are obtained at the excitation of 980 nm laser. The emission intensity can be increased by heat treatment. The glass-ceramic samples heat-treated at 880℃ for 50 min perform the strongest upconversion luminescence with intensity (at 545 nm) as 11 times high as that of the precursor glasses, which can be ascribed to the dense columnar crystals embedded in the glass matrix and the enrichment of Nd3+ ions in the crystals.

Key words: glass-ceramics, aerodynamic levitation method, heat treatment, upconversion luminescence
