Abstract
(EN)
Provided are a preparation method for graphene quantum dots with different oxygen content, a graphene quantum dot, and a fluorescent material. The preparation method comprises the following steps: dispersing graphene oxide in a peroxide solution to obtain a graphene oxide dispersion; mixing the graphene oxide dispersion with an alkali liquor and performing purification to obtain graphene quantum dot powder; and performing, after loading the graphene quantum dot powder on a carrier, gradient elution to obtain graphene quantum dots with different oxygen content. By means of the preparation method, oxygen content of a graphene quantum dot is controllable, and thereby an emission wavelength of a product is controllable, providing a reliable foundation for applications of the graphene quantum dot in fields such as LED and cell marking. The method also features simple and easy operations.

La présente invention concerne un procédé de préparation de points quantiques de graphène ayant différentes teneurs en oxygène, un point quantique de graphène, et un matériau fluorescent. Le procédé de préparation comprend les étapes suivantes : dispersion d’oxyde de graphène dans une solution de peroxyde pour obtenir une dispersion d’oxyde de graphène ; mélange de la dispersion d’oxyde de graphène avec une liqueur alcaline et exécution d’une purification pour obtenir une poudre de point quantique de graphène ; et exécution, après la charge de la poudre de point quantique de graphène sur un support, d'élution par gradient pour obtenir des points quantiques de graphène ayant différentes teneurs en oxygène. À l’aide du procédé de préparation, il est possible de réguler la teneur en oxygène d’un point quantique de graphène, et de là une longueur d’onde d’émission d’un produit peut être régulée, offrant une base fiable aux applications du point quantique de graphène dans les domaines tels que les LED et le marquage de cellules. Le procédé concerne en outre des opérations simples et faciles.
