We report on the photoconductive UV detector on sol-gel synthesized ZnO film based on Au-ZnO metal-semiconductor junction. I-V characteristics of these devices are perfect Ohmic in nature. Photocurrent is maximum at around 350nm, and later a more than two-fold drop in the value was measured above 400nm. Room temperature photoluminescence spectrum of ZnO exhibits two peaks, one in the UV region and...
