Novel Fabrication Method of Organic Metal Hetero Nano-Interface and Optoelectronic Function

本项目成功建立了“光催化还原法”，作为一种通用技术制备有机-金属异质纳米界面，如聚二乙炔纳米晶（芯）/金属（Ag）；Au，和Pt)杂化纳米晶体。当进行Z-Scan测量时，证实了这些杂化纳米晶体的非线性光学性质增加，这是由于金属纳米壳结构的局域表面等离子体引起的光电场增强。

In the present project, "Photo-catalytic reduction method" has been successfully established to fabricate organic-metal hetero nano-interface as a common technique, e.g., polydiacetylene nanocrystal (core)/metal (Ag.Au, and Pt) hybridized nanocrystals. The nonlinear optical property of these hybridized nanocrystals wereconfirmed to increase, due to the enhancement of optical electric field induced by localized surface plasmon from metal nano-shell structure, when so-called Z-Scan measurement has been carried out.
