摘要

采用高温熔融法和热处理工艺制作了含有GdF

纳米晶的氧氟微晶玻璃。在386nm激发下

掺杂氧氟微晶玻璃的发光强度明显增强

且蓝光对黄光的发光强度比逐渐增大

表明Dy

已进入到GdF

纳米晶中。在980nm激光器泵浦下

共掺氧氟微晶玻璃的上转换发光随着热处理温度的升高明显增强

的上转换发光出现明显的Stark分裂现象

这亦说明Er

已进入到GdF

纳米晶相中。通过研究上转换发光强度与泵浦功率的关系

确定绿光上转换发光为双光子过程。

Abstract

The transparent oxyfluoride glass ceramics containing GdF

nanocrystals were prepared by high-temperature melting and heat treatment method.Comparison with the as-prepared glass

doped oxyfluoride glass ceramics exhibit higher emission intensity excited at 386 nm and the intensity ratio between blue light and yellow light emission increases gradually with the heat treatment temperature

which indicates that Dy

ions have participated into the precipitated GdF

nanocrystals.Under the excitation of 980 nm laser diode

the upconversion luminescence intensity increases gradually with the heat treatment temperature and the upconversion luminescence peaks appear apparent Stark splitting phenomenon

which also demonstrates Er

ions have entered into the precipitated GdF

nano-crystalline phase.Based on the relationship between excited power and the upconversion intensity in Er

doped glass ceramic GC-650

two-photon absorption process was determined for the green upconversion emission of Er
