Plasmonic Nature of the “Blue State” in the WO3 Photoelectrode: Carrier Dynamics and Its Impact on Photoelectrochemical Water Oxidation

Abstract This study discusses the photophysical nature of the commonly observed “blue state” in WO3 photoanodes during photoelectrochemical water splitting. We demonstrate, using ultrafast transient absorption spectroscopy, that photoexcitation of the blue state of WO3, generated...

Intrinsically Conductive Films of Ag2Te Nanocrystals for Broadband Infrared Photodetection beyond 2000 nm

Abstract We report a rapid, up-scalable synthesis in an aprotic solvent to obtain Ag2Te nanocrystals that are intrinsically capped with a short, conductive thiol ligand, making them suitable for optoelectronic applications. The simultaneous use of labile and stable tellurium prec...
