Abstract Zinc (Zn) nanoplates were successfully manufactured using anodic aluminum oxide (AAO) template-assisted electrochemical deposition under controlled current–time transient throughout a specific electrochemical-deposition period via potentiostat. The Zn nanoplates-AAO assembly was oxidized inside a tubular furnace under optimized atmosphere to create significant ZnO nanoplates-AAO assembly features. The extreme morphological and structural properties of the ZnO nanoplates-AAO assembly were employed to construct perfect-photoresponse UV photodetector. The electrical behavior and photoresponse performance were inspected and the outcome confirmed UV photodetection under irradiation (365 nm, 2.62 mW/cm2) with large-sensitivity (1800), quick rise-time (1.2 s) and quick fall-time (1.19 s) under a constant 5 V applied-bias. The photodetector showed a remarkable reproducibility and stability with time. Hence, the photodetector based on ZnO nanoplates-AAO assembly presented in this research can be considered as a potential nano-optoelectronic device that is favorable in near UV-region detection.
