中文摘要：
以应用于薄膜太阳电池为目的,采用水热法制备了掺杂稀土离子的纳米氟化钇钠上转换荧光材料.研究了稀土离子Yb3＋/Er3＋单独和共同掺杂对材料的晶体结构和光学性质的影响.制备的Yb3＋/Er3＋共掺材料兼顾了两种稀土离子的光吸收谱,吸收980nm和1530nm附近的红外光,并发出能够被薄膜太阳电池有效吸收利用的红光（653nm）和绿光（520,540nm）.优化出较为合适的18%Yb3＋,2%Er3＋的掺杂比例,获得了具有较好上转换效果的纳米荧光颗粒材料.
英文摘要：
Nanocrystals of up-conversion phosphor, rare earth-doped sodium yttrium fluoride were prepared by hydro-thermal method for the application in thin film solar cells. Effect of Yb^3＋ and/or Er^3＋ doped materials on the crystal structure and optical properties were studied. Up-conversion materials with Yb^3＋/Er^3＋ co-doped absorb the infrared near 980 nm and 1530 nm and emit red （653 nm）and green （520 nm, 540 nm）light, which is well adapted for use in thin film solar cells. Nanoparticels with efficient near-infrared to visible up-conversion fluorescence with appropriate doping concentrations of 18% Yb^3＋ and 2% Er^3＋ were prepared.
