A zinc oxide (ZnO) nanoparticle photodetector was fabricated using a simple method. Under a 5V applied bias, its dark current and photocurrent were 1.98 10 -8 and 9.42 10 -7 A, respectively. In other words, a photocurrent-to-dark- current contrast ratio of 48 was obtained. Under incident light at a wavelength of 375nm and a 5V applied bias, the detectors measured responsivity was 3.75A/W. The transient time constants measured during the turn-ON and turn-OFF states were ON =204s and OFF =486s, respectively.
