摘要
I-III-VI族半导体纳米材料是一类具有优异光电性质的功能材料,在新一代低成本太阳能电池、生物荧光标记、发光二极管、可见光光催化等领域具有重要的应用前景,近年来吸引了人们极大的研究兴趣~[1]。然而,因其含有两个不同的金属离子,具有复杂的晶体结构和组成,导致可控制备它们是一个巨大的挑战。在此,我们发展了一种简便方法,即AgNO_3、InCl_3、十二硫醇以及二苯基二硒的混合物在高温下发生热分解反应,得到了AgInS_(2(1-x))Se_(2x)多级纳米结构(见Fig.1所示)。该多级结构由一维纳米线自组装构成。随着二苯基二硒用量的增加,多级纳米结构相对松散。在该反应中,十二硫醇一方面充当硫源,一方面充当反应溶剂以及表面活性剂。
I-III-VI semiconductor nanomaterials have important applications in many fields such as solar cells, light-emitting diodes, biological investigations, photocatalyst due to their outstanding electro-optical properties. However, it is a challenge to synthesize their nanomaterials in a controlled manner due to their flexible compositions structures. Herein, we report a facile synthesis of Ag In S_(2(1-x))Se_(2x) hierarchical nanostructure by thermolysis of a mixed solution of AgNO_3, InCl_3, n-dodecanethiol and diphenyl disenenide at elevated temperature. The hierarchical nanostructures were composed of one-dimensional nanowires. In particular, the nanostructures become loose as the increase of diphenyl disenenide. In our reaction system, dodecanethiol acted as sulfur source, surfactant and solvent.
