Preparation of carbon-based quantum dots and metal nanocomposites and their applications in sensors

Abstract

Carbon-based quantum dots, zero-dimensional carbon nanomaterials that can be widely used with a particle size of 1-10nm, can be widely used in fluorescent carbon nanomaterials in thousands of households. This article will first elaborate on carbon-based quantum dots and metal nanomaterials and explain the related methods of making them. First, the top-down method is used to prepare carbon quantum dots, the fluorescence mechanism of carbon-based quantum dots is used, and the electrochemical method is used at high temperature. Carbonization burning method and laser ablation method, the mixture of graphite powder and polyethylene glycol ester is hot pressed, baked, and cut in an argon atmosphere to obtain strong fluorescent carbon-based quantum dots, and then explain the immune algorithm to prepare nanocomposites for cermet mold materials, use the diversity of antibodies to calculate the concentration and quantity, and calculate its viability. Through regression coefficients, it can be shown that the immune algorithm is used to optimize the component optimization design of Ti(C,N)-based nanocomposite cermet mold materials. The effect is better.
