Zinc oxide is a low cost and practical II-VI chemical material, which is utilized to absorb silver (Ag) nanoparticles (NPs) on zinc oxide nanosheets (ZnO NSs). Using the Ag NP-decorated ZnO NSs can improve the electrical characteristics of zinc oxide. Field electron emission characteristics of ZnO NSs and Ag-ZnO NSs indicate the turn-on fields were 5.3 and 3.2 V/μm in the dark, whereas the turn-on field were 4.3 and 2 V/μm under UV light, respectively. In addition, the field electron emission characteristics of ZnO NSs and Ag-ZnO NSs indicate the enhanced field enhancement factors were 3002 and 3420 in the dark and 3276 and 4815 under UV light, respectively.
氧化锌是一种低成本且实用的II-VI族化学材料，它被用于在氧化锌纳米片（ZnO NSs）上吸附银（Ag）纳米颗粒（NPs）。使用装饰有Ag NPs的ZnO NSs可以改善氧化锌的电学特性。ZnO NSs和Ag-ZnO NSs的场电子发射特性表明，在黑暗中开启场分别为5.3和3.2 V/μm，而在紫外光下开启场分别为4.3和2 V/μm。此外，ZnO NSs和Ag-ZnO NSs的场电子发射特性表明，在黑暗中增强的场增强因子分别为3002和3420，在紫外光下分别为3276和4815。
