Abstract

The invention provides a preparation method of a gold nano-particle cup and a gold nano-particle bottle. The preparation method comprises the steps that (1) a lead sulfide nano-particle solution is prepared; (2) a lead sulfide gold hybrid nano-structure is prepared; (3) a lead sulfide template is removed selectively; and (4) the gold nano-particle cup or the gold nano-particle bottle is obtained. Through the preparation method, the lead sulfide gold hybrid nano-structure, the gold nano-particle cup and the gold nano-particle bottle can be obtained.

Description

Technical field [0001] The invention relates to the technical field of preparation of gold nanoparticles, in particular to a method for preparing a gold nano cup or a gold nano bottle based on a template method. Background technique [0002] Gold nanoparticles have good chemical stability and excellent physical and chemical properties. Due to the high free electron density and high conductivity of gold, gold nanoparticles exhibit excellent surface plasmon resonance properties. When resonance occurs, gold nanoparticles have a very high electric field strength enhancement effect, a great optical absorption and scattering cross-section. These properties have shown great applications in the fields of optical control, biotechnology, optoelectronic technology, solar technology, and microelectronics technology. prospect. [0003] So far, gold nanoparticles with a variety of morphologies have been prepared, such as gold nanospheres, gold nanorods, gold nanobicones, gold nanosheets, and g...
