 Aluminum doping and ultraviolet light exposure can significantly enhance the gas-sensing properties of zinc hydroxyl fluoride, ZNOHF, making it more sensitive to nitrogen dioxide at lower temperatures than before. This is due to the increased electron concentration caused by the aluminum dopant, which facilitates electron transfer between the nanorod structures and reduces the band gap, allowing for faster charge transport. Additionally, the photo-generated electrons and holes from the ultraviolet light have high activity, leading to more efficient gas adsorption and desorption processes. Together, these effects lead to a higher sensitivity to nitrogen dioxide and a shorter response slash recovery time. This article was authored by Xinyu Yao, Riteo Wang, Lily Wu, and others.
