从夹心细胞中观察到强烈的电化学发光（ECL）。电池结构如下：乙腈/F掺杂SnO 2 中的F掺杂SnO 2 /纳米孔TiO 2 /三(2,2'-联吡啶基)钌(II)络合物[Ru(bpy) 3 (PF 6 ) 2 ]。仅当负电池电压施加到纳米多孔TiO 2 电极时才观察到强烈的ECL。 ECL随着多孔TiO 2 层表面积的增加而增加。对于多孔ZnO 电极观察到ECL 增加，但对于多孔SnO 2 电极则没有观察到ECL 增加。结论是ECL的增加与多孔TiO 2 电极中Ru + 的形成以及多孔电极中Ru 2 + 还原后发生的过程有关。
Intense electrochemiluminescence (ECL) was observed from sandwich cells. The cell structure is as follows: F-doped SnO 2 /nanoporous Ti02/tris(2,2'-bipyridyl)ruthenium(II) complex [Ru(bpy) 3 (PF 6 ) 2 ] in acetonitrile/ F-doped SnO 2 . Intense ECL was observed only when negative cell voltage was applied to nanoporous TiO 2 electrodes. The ECL increased with an increase in the surface area of porous TiO 2 layers. ECL increase was observed for porous ZnO electrodes, but not for porous SnO 2 electrodes. It was concluded that increases in ECL are associated with the formation of Ru + in porous TiO 2 electrodes and the process taking place after reduction of Ru 2 + which occurs in the porous electrodes.
