|
Electrochemiluminescence (ECL) cell using the electrode of TiO2 nanotube (NT) and Ru(ll) complex Ru(bpy)3(PF6)2 as a luminacence substance was fabricated. TiO2 NT were produced from the membrane of TiO2 NT arrays fabricated by anodic oxidation of approximately 100 microm thick Ti-plate. TiO2 NT arrays inject increasing number of electrons to the Ru(II) complex at the interface of TiO2 NTs. It allows the increasing exergonic oxidation/reduction reaction of Ru(II) complex. The ECL cell emits approximately 600 nm light in orange color. The cell structure is composed of a glass/F-doped SnO2(FTO)/TiO2 NT/Ru(II) complex in propylene carbonate/FTO/glass. The ECL efficiency of the cell consisting of the layer of TiO2 NT was approximately 255 cd/m2 at a bias of 4 V. The use of TiO2 NT increases ECL intensities by 5 times compared to the typical ECL cell without the use of TiO2 NT. |
