In this study, zinc oxide (ZnO) thin films were utilized to create metal-semiconductor-metal (MSM) structured ultraviolet (UV) photodetectors using laser assisted chemical bath deposition (LACBD). For the first time, LACBD has successfully manufactured zinc oxide (ZnO) nanoclusters (NCs) with high-quality structural, optical, and electrical properties on a glass substrate coated with iron (Fe) to construct an MSM UV photodetector with high responsivity. The thin film was created by irradiating the chemical bath in situ using a continuous wave semiconductor laser with wavelength(460 nm), output power (1 W), and irradiation laser time (30 min). The thin film was characterized using field emission scanning electron microscopy (FE-SEM), energy dispersive Xray (EDX) analyses, and X-ray diffractometry (XRD). Our findings revealed that LACBD promoted the development of a high-crystallinity ZnO thin film. The effectiveness of ZnO NCs in UV detection has also been examined to account for the potential of these nanostructures. The device's current-voltage (I-V) characteristics were tested in dark and light situations, confirming the UV photodetector's excellent responsiveness and stability. Optical confinement, a high surface-tovolume ratio, and the superior structural quality of the NCs, as confirmed by time-resolved spectroscopy, are all factors in the great photodetector performance.
