Abstract
Zinc oxide is a low-cost and practical II–VI chemical material, which is utilized in the form of zinc oxide (ZnO) nanorods to absorb platinum (Pt) nanoparticles (NPs). Using Pt NPs to decorate ZnO nanosheets (NSs) can improve the electrical characteristics of zinc oxide. A set of samples has been prepared for different prerequisite Pt precursors with 0- and 30-s sputter deposition times. The SEM results indicate that ZnO NSs and Pt ZnO NSs have an average diameter and length of ~30 nm and $\sim 1.08~\mu \text{m}$ and ~30 nm and $\sim 1.25~\mu \text{m}$ , respectively. The surface topography of ZnO NSs and Pt ZnO NSs showed no obvious difference. The results of ZnO NSs and Pt ZnO NSs indicate that the turn-ON field was 5.8 and 3.8 V/ $\mu \text{m}$ in the dark and that the turn-ON field was 3.9 and 2.9 V/ $\mu \text{m}$ under UV light, respectively.
