More Information
Summary:The invention discloses a graphene quantum dot complex and a preparation method thereof and an application thereof in being used as a calcium ion detection solution. According to the invention, a luminophore is introduced to a nano quantum dot with environmental friendliness, specifically, dopamine hydrochloride is introduced to a graphene quantum dot, so that a graphene quantum dot complex type fluorescent compound with ultrastrong water solubility and high calcium ion selectivity is obtained; a synthesis method of the compound is simple and mild in conditions, and products are easy to obtain; and after the compound is applied to the calcium ion detection in the invention so as to achieve a good effect, the invention is implemented. The graphene quantum dot complex disclosed by the invention is formed by connecting a graphene quantum dot with luminescent properties and good water solubility with the fluorophore through an amido bond, so that a compound with dual luminescent properties is formed.
