Title:
GOLD NANOPARTICLE-PHOSPHOR HYBRID MATERIAL AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2021/010545
Kind Code:
A1
Abstract:
The present invention relates to a gold nanoparticle-phosphor hybrid material with improved fluorescence intensity and stability and a method for preparing same and, more specifically, to a gold nanoparticle-phosphor hybrid material, a method for preparing same, and a biosensor and a light emitting device for a display, each using same, wherein the gold nanoparticle-phosphor hybrid material comprises: a gold nanoparticle in the form of a polyhedron enclosed by six squares; carbon quantum dots; and polyglycol connecting the gold nanoparticle and the carbon quantum dots. The present invention provides the gold nanoparticle-phosphor hybrid material and the method for preparing same, and thus exhibits a metal-enhanced fluorescence (MEF) effect between the gold nanoparticle and the carbon quantum dots, and exhibits a fluorescence amplification effect depending on the distance between the gold nanoparticle and the carbon quantum dots or the concentration of the carbon quantum dots, thereby controlling the fluorescence intensity of the hybrid material. In addition, compared with a conventional fluorescent substance, the hybrid material of the present invention has a long lifetime and a simple synthesis process, shows no toxicity, and is connected to the gold nanoparticle which is chemically very stable, to have an increased storage period, thereby having high economical efficiency and facilitating control, adjustment, and handling of optical properties.
