| 摘 要： | 通过熔融法以及热处理,制备了Ce~(3+)掺杂含Li Lu F_4纳米晶的透明氟氧微晶玻璃。XRD结果表明,玻璃中析出的晶相为Li Lu F_4,其晶粒大小随热处理温度的升高和时间的延长而变大。在330 nm紫外光激发下,Ce~(3+)掺杂的氟氧玻璃和Li Lu F4微晶玻璃的发射为一峰值波长为370 nm的宽带光谱。微晶玻璃的发光强度显著高于未经过热处理的基础玻璃,并且随着热处理温度的升高及时间的延长,微晶玻璃的发光逐渐增强。微晶玻璃的370 nm发射的荧光寿命均长于基础玻璃的。

| Abstract: | Transparent Ce3+ doped glass ceramics containing LiLuF4 nanocrystals were prepared by melt-quenching method with subsequent heat treatment. XRD results show that the precipitated crystalline phase in the glass matrix is LiLuF4 . Under 330 nm light excitation, Ce3+ doped oxyfluoride glass ceram-ics containing LiLuF4 nanocrystals show more intense emission than the as-made glass, and the emission intensity increases with the increasing of heat treatment temperature and time. The lifetimes of 370 nm emission of Ce3+ doped oxyfluoride glass ceramics are longer than that of as-made glass. |
