Abstract
Near ultraviolet light is widely applied for bactericidal treatments. In order to study the relation between bacteria inactivation and light power, near-UV sensors with low detection limit and high sensitivity are desired. Based on previous research results of applying wide bandgap metal oxide semiconductors for UV/near-UV sensors, we developed an in-situ fabrication process for ZnO nanoparticle-based near-UV sensors using high current density electrodeposition and flame oxidation. The developed sensors exhibit microporous texture decorated with nanoparticles. The sensors showed well-defined near-UV responses with high sensitivity and fast recovery.
