Preparation method of crystal-induced orange red luminescent solid carbon dots

The invention relates to the technical field of nano material preparation, in particular to a preparation method of crystal-induced orange red luminescent solid carbon dots. The preparation method comprises the following steps: (1) fully dissolving weighed phthalic acid and thiourea medicines into an N, N-dimethylformamide solvent or an ethanol solvent to obtain a solution; (2) carrying out microwave reaction on the solution obtained in the step (1); (3) purifying the reaction solution obtained in the step (2) by using deionized water; and (4) drying and grinding the purified sediment to obtain solid carbon dot powder. The solid-state light-emitting quantum yield of the preparation method reaches 17%, and the preparation method has the advantages of being small in solvent dosage, simple in preparation process and high in repeatability. 本发明涉及纳米材料制备技术领域，尤其涉及一种结晶诱导橙红色发光固态碳点的制备方法。该制备方法包括如下步骤：(1)将称量的邻苯二甲酸和硫脲药品充分溶解到N,N-二甲基甲酰胺溶剂或乙醇溶剂中，得溶液；(2)将步骤(1)得到的溶液进行微波反应；(3)将步骤(2)得到的反应溶液使用去离子水进行提纯；(4)将提纯的沉积物烘干、研磨，得固态碳点粉末。该制备方法的
