通过水热-垂直沉积法制备了一种新型的荧光光子晶体薄膜,得到的荧光光子晶体具有鲜艳的色彩和良好的荧光性能.此薄膜在460 nm处有明显的反射峰,在440 nm处有很强的荧光峰.将此荧光光子晶体薄膜作为染料敏化太阳能电池背反射层时,可以将开路电压由0. 75 V提高到0. 77 V,短路电流由7. 64 mA/cm2提高到8 mA/cm2,光电转换效率由4. 13%提高到4. 23% ,可以提高2. 42%的光电转换效率.%A novel kind of fluorescent photonic crystal ( FPC ) films was generated by hydrothermal-vertical deposition method,exhibiting brilliant structural color and good fluorescence simultaneously. The FPC films have a strong reflection peak at 460 nm and a strong fluorescence peak at 440 nm. When fluorescent photonic crystal films are used as the back-reflecting layers of dye-sensitized solar cells, the photoelectric conversion efficiency increases from 4. 13% to 4. 23% .
