中文摘要：

Y (哦)₃:Eu³⁺ nanotubes 用一个灵巧的热水的方法被综合，然后，磅粒子在使用真空抽取的联合并且退火的 nanotubes 的表面上被种。产生 Pt/Y ₂ O ₃:Eu³⁺合成 nanotubes 不仅在 255-nm 或 468-nm 刺激下面展出了提高的红光而且能也被用来改进敏化染料的太阳能电池的效率，导致8.33%的效率，没有合成 nanotubes ，它与一节太阳能电池相比代表11.96%的重要改进。电气化学的阻抗光谱学结果显示 TiO ₂-dye|I ₃^-/I ^- 电解质的界面的抵抗 TiO ₂-Pt/Y₂ 合成房间多是的 O ₃:Eu³⁺ 比一个纯 TiO ₂ 房间的小。另外， TiO ₂-Pt/Y₂ O ₃:Eu³⁺ 合成房间比纯 TiO ₂ 房间展出了一更短的电子运输时间和更长的电子再结合时间。

英文摘要：

Y（OH）3：Eu3＋ nanotubes were synthesized using a facile hydrothermal method, and then, Pt particles were grown on the surface of the nanotubes using a combination of vacuum extraction and annealing. The resulting Pt/Y2O3：Eu3＋ composite nanotubes not only exhibited enhanced red luminescence under 255- or 468-nm excitation but could also be used to improve the efficiency of dye- sensitized solar cells, resulting in an efficiency of 8.33%, which represents a significant enhancement of 11.96% compared with a solar cell without the com- posite nanotubes. Electrochemical impedance spectroscopy results indicated that the interfacial resistance of the TiO2-dyel I3/I- electrolyte interface of the TiO2-Pt/Y203：Eu3~ composite cell was much smaller than that of a pure TiO2 cell. In addition, the TiO2-Pt/Y2O3：Eu3＋ composite cell exhibited a shorter electron transport time and longer electron recombination time than the pure TiO2 cell.
