Photoinduced Electrochemiluminescence at Metal Oxides

The luminescence of fluorophores can be amplified in a very precise manner at the metal-oxide/liquid interface by photogenerated holes.
Photoinduced Electrochemiluminescence at Metal Oxides

Photoelectrochemistry is useful to several important applications. First, when photoelectrochemistry is used with a semiconductor surface illuminated with sunlight, it can convert solar energy into solar fuels. In addition, photoelectrochemistry can also generate light from an electric current, which is the basis for ultra-sensitive sensors, widely used for biomedical purposes. By combining these two fields of photoelectrochemistry that are not frequently mixed together, Jing Yu (ISM, Bordeaux), Hiba Saada (ISCR, Rennes), Rawa Abdallah (Lebanese University), Gabriel Loget (ISCR, Rennes) and Neso Sojic (ISM, Bordeaux) and have designed a system, based on a metal oxide-based semiconductor (BiVO4) and a luminol derivative, capable of amplifying the light emission of a fluorescent solution. This research has been lately reported as a “hot paper” in the journal Angewandte Chemie.
