WebMar 2, 2024 · Here, we are demonstrating a photodoping-inspired gas sensing approach based on a thin solid film made of ultrasmall (<5 nm) TiO2 nanoparticles. The gas sensing material has been activated by UV... WebPhotodoping is a method for tuning the carrier densities of semiconductor nanocrystals. By exposing the crystal to a specific wavelength of light from an LED tens to hundreds of conduction band electrons per nanocrystal can be accumulated. Zinc oxide nanoparticles viewed through a scanning electron microscope, or SEM.
