摘　　要：采用水热法合成了La3+离子掺杂的TiO2 纳米粒子 (La3+掺杂量 0 .5mol% ) ,并用光电化学方法研究了Ru(bpy) 2 (NCS) 2 (bpy =2 ,2’_bipyridy1_4 ,4’_dicarboxylicacid)敏化La3+掺杂的TiO2电极 (简写为La3+_TiO2 )的光电化学行为 .实验证明Ru(bpy) 2 (NCS) 2 敏化La3+_TiO2The La 3+ _doped TiO 2 nanoparticles were prepared with hydrothermal method.The photoelectrochemical properties of La 3+ _doped TiO 2 nanoporous_film electrode sensitized by Ru(bpy) 2(NCS) 2 were studied.The conversion efficiency of light to electricity and the energy conversion efficiencies were ineased with the depth of La 3+ _doped TiO 2 nanoporous_film electrode.
