为了寻找等离子纳米结构的广泛应用，复合材料比纯贵金属更受欢迎。为了获得行为可控的复合材料，半金属和贵金属的组合是有趣的选择，因为半金属的性质更像贵金属，并且可以通过成分来调节。将金属银和半金属TiS_2共溅射到二维聚苯乙烯(PS)模板上，形成弯曲的单层TiS_2-Ag纳米结构，其组成可以通过TiS_2的溅射功率来调节。TiS_2的含量可以调节LSPR从可见光区向近红外区的移动。当TiS_2的溅射功率为120W时，TiS_2-Ag纳米结构的增强因子可达10(9)。
To find wide applications of plasmonic nanostructures, the composite materials are preferred to the pure noble metals. To get the composites with the controllable behaviors, the combinations of the semi-metals and the noble metals are the interesting choices, because the semi-metals have the properties more like the noble metals and can be tuned by the compositions. The mental Ag and semi-mental TiS2 are co-sputtered on the two-dimensional polystyrene (PS) templates to form the curved single-layer TiS2-Ag nanostructures, for which the compositions can be tuned by the sputtering power for TiS2. The content of TiS2 can regulate the LSPR shifts from visible region to NIR region. When the sputtering power of TiS2 is 120 W for the TiS2-Ag nanostructures, the enhancement factor can reach 10(9).
