成功制备了含立方NaYF 4纳米晶的透明氟氧化物硼硅酸盐玻璃陶瓷。X射线衍射和透射电子显微镜结果表明，在玻璃基体中析出了平均粒径为30 nm的立方相NaYF 4纳米晶。结果表明，Er 3 +/Yb 3+共掺透明微晶玻璃的上转换发光强度明显增强，这可能是由于晶化后Er 3+和Yb 3+离子的配位环境发生了变化。该材料的高透明性、强烈的上转换发光以及简单、低成本的制备工艺使其在非晶硅太阳能电池领域具有潜在的应用前景。
Transparent oxyfluoride borosilicate glass ceramic containing cubic NaYF4nanocrystals were successfully fabricated. The cubic NaYF4nanocrystals with average size of 30 nm were precipitated in the glass matrix, which was confirmed by the X-ray diffraction and TEM results. In comparison with the as-made glass, significant enhancement of upconversion luminescence is observed in the Er3+/Yb3+codoped transparent glass ceramic, which may be due to the variation of coordination environment of Er3+and Yb3+ions after crystallization. The high transparency, intense upconversion luminescence and the simple, low-cost fabrication process make this material exhibiting potential applications in the fields of amorphous silicon solar cells.
