中文摘要:

Rh6G-Au-AAO 的高度订的 nanocomposite 数组被用玫瑰精 6G (Rh6G ) 和金 nanoparticles 填满阳极化的铝氧化物(AAO ) 形成。Rh6G-Au-AAO 的光性质被可见吸收性、荧光灯的光谱学学习。与在答案环境的 Rh6G-Au 的荧光系列相比, Rh6G-Au-AAO 的荧光山峰紧张显著地被提高,最大的改进率是 5.5,并且山峰位置的 12 nm 的经常的蓝移动被介绍。效果来自 AAO 的空间监禁和熄灭金 nanoparticles 导致的效果的荧光的抑制。结果证明荧光分子金属 nanoparticles-AAO 的 nanocomposite 结构在设计分子的集会并且为未来 nanophotonics 创造优异性质的功能的材料有一个可观的潜力。

英文摘要:

Highly ordered nanocomposite arrays of Rh6G-Au-AAO are formed by filling anodized aluminum oxide (AAO) with Rhodamine 6G (Rh6G) and gold nanoparticles. The optical properties of Rh6G-Au-AAO are studied by visible absorptive and fluorescent spectroscopy. Compared with the fluorescence spectra of Rh6G-Au in the solution environment, the fluo- rescence peak intensities of Rh6G-Au-AAO are significantly enhanced, the maximum enhancement rate is 5.5, and a constant blue shift of-12 nm of peak positions is presented. The effects come from the spatial confinement of AAO and the inhibition of the fluorescence quenching effect induced by gold nanoparticles. The results show that the nanocomposite structures of fluorescence molecules-metal nanoparticles-AAO have a considerable potential in engineering molecular assemblies and creating functional materials of superior properties for future nanoDhotonics.
