摘要: 采用牺牲模板法在室温下原位硫化类球形Ag纳米颗粒制备得到Ag@Ag2S核壳结构。利用X射线粉末衍射(XRD)、透射电镜(TEM)和紫外-可见光谱仪(UV-Vis)等测试手段对样品进行分析表征。用实验室自组装的光热转换测试装置测试了Ag@Ag2S核壳结构及单组份Ag、Ag2S纳米颗粒的光热转换性能。结果表明:在808 nm激光的照射下,Ag@Ag2S核壳结构具有比单组分Ag、Ag2S纳米颗粒更优异的光热转换性能。

Abstract: Core@shell structures have excellent photothermal conversion properties. In this article, Ag@Ag2S core@shell structures were synthesized by a sacrificial template method through the sulfuration of quasi-sphere Ag nanoparticles at ambient temperature. The samples were characterized with X-ray powder diffraction (XRD), transmission electron microscopy (TEM) and UV-Vis-NIR spectrometer. The photothermal conversion properties of Ag, Ag2S nanoparticles and Ag@Ag2S core@shell structures were studied on a lab-made evaluation system. The results show that the Ag@Ag2S core@shell structures have enhanced photothermal conversion properties in comparison to the Ag and Ag2S nanoparticles.

Key words: Ag@Ag2S; core@shell structures; photothermal conversion properties
