Photocatalytic and Antimicrobial Properties of Ag2O/TiO2 Heterojunction

ChemEngineering, 2019
Ag2O/TiO2 heterojunctions were prepared by a simple method, i.e., the grinding of argentous oxide with six different titania photocatalysts. The physicochemical properties of the obtained photocatalysts were characterized by diffuse-reflectance ...

Theory predicts UV/vis-to-IR photonic down conversion mediated by excited state vibrational polaritons

Nature Communications, 2023
This work proposes a photophysical phenomenon whereby ultraviolet/visible (UV/vis) excitation of a molecule involving a Franck-Condon (FC) active vibration yields infrared (IR) emission by strong coupling to an optical cavity.
