Abstract

We present fluorescence and a random lasing enhancement effect due to the interaction between gold nanoparticles (AuNPs) and Rhodamine 6G (Rh6G) dye. Non-covalently bounded dyes in the proximity of nanoparticles are studied in three systems of varying dimensionality: from (i) three-dimensional freely distributed suspensions, through (ii) quasi-two-dimensional multilamellar liposomes, to (iii) solid two-dimensional thin layers. Liposomes facilitate the formation of stable AuNPs/Rh6G composition showing enhanced fluorescence, while solid thin films exhibit plasmon-assisted random lasing.

摘要

我们展示了由于金纳米颗粒（AuNP）与罗丹明6G（Rh6G）染料之间的相互作用而产生的荧光和随机激光增强效应。在三种不同维度的体系中研究了纳米颗粒附近非共价结合的染料：从（i）三维自由分布的悬浮液，到（ii）准二维多层脂质体，再到（iii）固态二维薄膜。脂质体促进形成显示增强荧光的稳定AuNP/Rh6G组合物，而固态薄膜则表现出等离子体辅助随机激光发射。
