Abstract

The invention relates to capsule gold nano particles with a double adsorbing property in a visible light region and a preparation method thereof. The capsule gold nano particles have the characteristics of being uniform in size, good in dispersibility and the like. The ratio of length to diameter of the nanoparticles can be effectively regulated within a range of 1: 1 to 5:2. The preparation method comprises the following steps: (1) preparing gold nanodecanedrons different in size in ethylene glycol by virtue of a polyhydric alcohol reduction method by taking poly diallyldimethylammonium chloride as a stabilizer and a morphological control agent; and (2) in a stirring condition, adding a certain amount of a gold decanedron nanoparticle colloidal solution into an ethylene glycol solution comprising poly diallyldimethylammonium chloride, chloroauric acid and ascorbic acid, and performing a reaction at a temperature of 0-100 DEG C for 30-180 minutes to obtain the capsule gold nanoparticle colloidal solution. The capsule gold nanoparticles obtained by the invention has a double adsorbing property in the visible light region, and has important application value and a wide application prospect in the aspects of solar utilization, photothermal conversion, biological / chemical sensing, medical diagnosis and the like.
