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- A nd 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 ∼ 1.08 μm and 30 nm and ∼ 1.25 μm, 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/μm in the dark and that the turn-ON field was 3.9 and 2.9 V/μm under UV light, respectively.
