Photoinduced electrochemiluminescence at nanostructured hematite electrodes
Résumé
In this article, we study the photoinduced electrochemiluminescence (PECL) of a luminol analog (L-012: 8-amino-5-chloro-2,3-dihydro-7-phenyl-pyrido[3,4-d]pyridazine-1,4-dione) on n-type hematite (-Fe 2 O 3) nanorod arrays deposited by hydrothermal synthesis on a transparent conducting oxide. We report that this material, when used as a photoanode, triggers PECL at a potential as low as-0.2 V vs Ag/AgCl and allows the amplification of the luminescence signal. The PECL concept should open up new perspectives based on lightaddressable strategies in bioanalysis and imaging.
