| 摘 要： | 我们采用层接层自组装技术将多金属氧酸盐H3PMo12O40(PMo12)和有机荧光染料藏红(ST)组装成多层复合膜。除了对膜进行UV-vis光谱,XPS光谱,IR光谱,荧光淬灭性质的表征外,还对膜进行了原子力显微镜表征。进一步深入的讨论了有机染料的荧光淬灭性质,为有机染料荧光淬灭性质的应用提供了有用信息。

| Abstract: | Ultrathin multilayer films of a polyoxometalate cluster H3PMo12O40(PMo12) and a fluorescence dye(ST) have been prepared by the layer-by-layer(LbL) self-assembly method.The PMo12/ST multilayer films have been characterized by X-ray photoelectron spectra(XPS),infrared spectra(IR),and fluorescence spectra.UV-vis measurements reveal regular film growth with each PMo12/ST adsorption and the difference between multilayer and PMo12/ST mixture solution.Fluorescence spectra showed that polyoxometalates caused the fl... |
