采用碳酸钠前驱体法制备Er3+,Yb3+:Y2O3纳米晶上转化材料,并在P25中掺杂制备上转化纳米tio2粉体。采用原子力显微镜(AFM)和x射线衍射仪(XRD)对上转化纳米颗粒的微观形貌、结构和粒径进行了表征。将具有上转换性能的纳米tio2粉末应用于染料敏化太阳能电池中,上转换材料制备的DSSC的光电转换效率是普通DSSC在红外光照射下光电转换效率的2倍。
Er3+ ,Yb3+ :Y2O3 nanocrystal up-conversion material has been prepared using the sodium carbonate precursor method and doped in the P25 to prepare up-conversion nano-TiO2 powder. The micromorphology, structure and particle size of the up-converting nanoparticles were characterized by atom force microscopy (AFM) and X-ray diffraction (XRD). Nano-TiO2 powder with up-conversion performance was applied to Dye-sensitized solar cells, the photoelectric conversion efficiency of the DSSC with up-conversion material is twice the photoelectric conversion efficiency of normal DSSC irradiated by infrared light.
