基于银掺杂钠钙玻璃的荧光染料自发辐射增强
Spontaneous Emission Enhancement of Dye Based on the Silver-Doped Soda Lime Glass
钠钙玻璃 离子交换 银纳米颗粒 表面等离激元共振 荧光增强 soda-lime glass ion exchange silver nanoparticles surface plasmon resonance photoluminescence enhancement
摘要
本文通过离子交换和后续热处理的方法在钠钙玻璃中引入Ag纳米颗粒, 并将Ag掺杂的钠钙玻璃作为衬底增强了钠钙玻璃和荧光染料罗丹明6G(R6G)的荧光辐射。Ag纳米颗粒的表面等离激元散射增强了掺杂玻璃的荧光, 而R6G的增强荧光辐射则源于掺杂玻璃与荧光染料之间的辐射共振能量转移。
Abstract
Ag nanoparticles (NPs) are introduced into the soda lime glasses through ion exchange and subsequent heating process. Using the Ag-doped glass as the substrate, photoluminescence (PL) enhancement of dye Rhodamine 6G (R6G) and soda lime glasses was observed. The surface plasmon scattering effect was ascribed to the enhancement of luminescence from the Ag-doped glass, while the radiative resonance energy transfer from Ag-doped glass to R6G was the origination of the PL enhancement of R6G.
