Problems solved by technology

Most of the above-mentioned fluorescent materials use gold nanoclusters as raw materials, and the degree of enhancement of fluorescence intensity is limited. In addition, solvents such as methanol are used in the synthesis process, which is not conducive to environmental protection requirements; according to the material display, gold nanoclusters are orange, There are limitations during use

Abstract

The invention relates to a method for enhancing the fluorescence intensity of a copper nano-cluster. The method comprises: synthesizing copper nano-cluster powder, and then generating a composite material of the copper nano-cluster and a prussian blue analogue in situ from the copper nano-cluster powder, a transition metal salt solution and a transition metal cyanide. According to the invention, the copper nano-cluster and the prussian blue analogue are mutually combined to form the composite material of the copper nano-cluster and the prussian blue analogue, so that the the fluorescence intensity of the copper nanocluster is enhanced due to the confinement effect of the prussian blue analogue, and in the composite material, the copper nano-cluster is still kept in a dispersed state.

Description

technical field [0001] The invention belongs to the technical field of metal nano-cluster materials, and in particular relates to a method for enhancing the fluorescence intensity of copper nano-clusters. Background technique [0002] Fluorescent metal nanoclusters have attracted much attention as a new type of fluorescent nanomaterials. Metal nanoclusters refer to molecular-level aggregates composed of several to hundreds of metal atoms under the protection of certain molecular layers. Due to their unique physical, electrical, and optical properties, metal nanoclusters have shown promising applications in fields such as single-molecule optoelectronics, catalysis, bioimaging, and sensors. At present, most studies mainly focus on gold, silver and their alloy nanoclusters. As we all know, copper is more abundant and cheap in the earth's crust than gold and silver, so it is widely used in human's daily life. However, relatively little research has been done on copper nanoclu...
