We report for the first time the fabrication of a ZnO PD by SILAR involving the use of ethylene glycol. The average diameter of ZnO was around 100 nm. In addition, the obtained hexagonal ZnO thin films grew along the c-axis and with stronger intensity at the peak (002) plane; further, the films had a smooth surface morphology and showed high transparency in the visible spectral range. The fabricated ZnO PD was visible-blind with a cutoff wavelength around 350 nm. Under a 10 V applied bias, the measured dark current was 2.58μA and the photocurrent was 803 μA, and hence, the responsivities were 68.5 A/W for the ZnO PD.
