摘　　要：由局域表面等离子共振(LSPR)形成的周期性Ag纳米网络结构在深紫外到近红外波段的高透光透明导体中具有潜在应用,但纳米网络结构透射特性、导电特性及形态的关系仍有待进一步研究。首先,用有限元分析法从理论上分析了Ag纳米颗粒形态对LSPR特性的影响。然后,研究了沉积的Ag覆盖率对周期性纳米网络结构光透射特性的影响。最后,通过建立等效电阻模型,研究分析了Ag纳米网络结构的电阻率和透射率。结果表明,在沉积一定厚度的Ag纳米颗粒时可以获得具有较高透光性以及较小薄膜电阻的Ag纳米网络结构。The periodic Ag nanonetwork structure formed via localized surface plasmon resonance(LSPR)has potential applications in the deepultraviolet to nearinfrared wavelengths.However,the relationship between the transmission and conductivity characteristics and the morphology of the nanonetwork structure remains to be further studied.In this paper,first,the effect of Ag nanoparticle morphology on the LSPR characteristics is theoretically analyzed using finite element analysis.Then,the effect of the deposited Ag coverage on the light transmission properties of the periodic nanonetwork structure is investigated.Finally,by establishing an equivalent resistance model,the resistivity and transmittance of the Ag nanonetwork structure are studied and analyzed.The results show that Ag nanonetwork structure with higher light transmittance and lower sheet resistance can be obtained when Ag nanoparticles with a certain thickness are deposited.
