Abstract :
An ultraviolet photosensor based on ZnO nanoplates has been successfully fabricated. ZnO nanoplates was synthesized by sonochemical method and coated on Cu interdigitated electrodes. The method is simple, rapid and applicable to research prototypes for further studies of ZnO nanoplates for nano-device applications. The current-voltage (I-V) characteristics show linear behavior and the photosensor exhibits a response of ~803mA/W for UV light under 15 V bias. Compared to other nano detectors, the fabricated detector shows fast photo response with a rise time of 150 ms and fall time of 50 ms compared to the other nanomaterial based photosensors.
