| 摘 要： | 本文报道了一类组成为50SiO2-10Al2O3-20ZnF2-20SrF2-3YbF3-0.05ErF3(mol%)的氟氧化物玻璃陶瓷的制备及其量子剪裁发光行为。XRD和TEM分析结果显示,玻璃陶瓷中均匀分布有尺度10~40nm的SrF2析晶相。光谱研究表明,玻璃陶瓷在Er3+激发峰波长377nm激发下存在Er3+向Yb3+的有效能量传递,可实现包括量子剪裁效应在内的波长变换功能。随着热处理温度的升高,玻璃陶瓷的近红外977nm发光逐渐增强,荧光寿命显著增长。

| Abstract: | Preparation and quantum cutting luminescence behavior of 50SiO_210Al_2O_3-20ZnF_2-20SrF_2-3YbF_3-0.05ErF_3(mol%) glass ceramics were investigated.X-ray diffractometry(XRD) and transmission electron microscopy(TEM) results showed that SrF_2 nanocrystals distributed homogenously in glass hosts.The glass ceramics exhibited efficient energy transfer from Er~(3+) to Yb~(3+) and the quantum cutting luminescence under the excitation of Er~(3+) with the excitation peak centered at 377 nm.With the increase of heat t... |
