具有上/下转换发光特性的纳米结构玻璃陶瓷及其制备方法
摘要：
本发明公开一种具有上/下转换发光特性的玻璃陶瓷及其制备方法。该玻璃陶瓷采用熔体急冷法结合后续热处理制备，其组分和摩尔百分含量为：SiO2：35-60mol%；Al2O3：10-30mol%；YF3：5-25mol%；NaF：5-15mol%；Na2CO3：5-20mol%；TmF3：0.05-1.00mol%；YbF3：0-2mol%。该材料有望降低硅太阳电池的亚带隙光子损失和热化能损，从而提高电池的光电转换效率。
摘要（英）：

The invention discloses a glass ceramic with up / down conversion luminescent property and a preparation method thereof The glass ceramic is prepared by a melt quenching method combined with subsequent heat treatment, and comprises components of, by molar percentage,35-60 mol% of SiO2,10-30mol% of Al2O3,5-25mol% of YF3, 5-15mol% of NaF, 5-20mol% of Na2CO3, 0.05-1.00mol% of TmF3, and 0-2mol% of YbF3. The material is expected to reduce sub-band gap photon loss and thermal energy loss of a silicon solar battery, so as to improve photoelectric conversion efficiency of the battery.
