Embodiment Construction

[0029] In order to illustrate the present invention more clearly, the following embodiments are listed, but they do not limit the scope of the invention in any way.

[0030] The structural formulas of the main substances involved are:

[0031]

[0032] (1) The preparation method of aluminum organic complex:

[0033] ①. Prepare 1,10-phenanthroline absolute ethanol solution and 0.2 mol / L octahydroxyquinoline absolute ethanol solution with concentrations of 0.1 mol / L, respectively.

[0034] ②, the 10ml ethanol solution of 1,10-phenanthroline and 10ml concentration of 0.1mol / L Al(NO 3 ) 3 The ethanol solution was added into a 100ml one-necked flask, and then 10ml of the ethanol solution of octahydroxyquinoline was added to the above reaction, and stirred and mixed.

[0035] ③, finally, adjust the Ph to 7-8 with concentrated ammonia water with a mass concentration of 25%, and keep the temperature at 60° C. for 17 hours. After the reaction was completed, it was left to stand ...

Abstract

The invention relates to an aluminum organic coordination compound as well as a graphene oxide doped aluminum organic coordination compound fluorescence material. The structural formula of the aluminum organic coordination compound is as shown in the specification. In the preparation method of a light-emitting material, 8-hydroxyquinoline (HQ) serves as a first ligand, 1,10-phenanthroline (Phen) serves as a second ligand, an aluminum ion serves as a connecting body and the aluminum organic coordination compound is formed. The aluminum organic coordination compound and graphene oxide are combined to form the blue light excited graphene oxide doped aluminum organic coordination compound light-emitting material. The material provided by the invention has high light-emitting property and the preparation method is simple.

Description

Technical field: [0001] The invention belongs to the field of fluorescent powder materials excited by blue light, in particular to a graphene oxide-doped aluminum organic complex fluorescent material excited by blue light and a preparation method thereof. Background technique [0002] As a kind of mixed light, white light is realized by rationally matching the three colors of light according to the three-color principle of red, green and blue. The white light achieved by using LED ultraviolet light combined with three kinds of phosphors has low luminous efficiency and will cause damage to packaging materials and illuminated objects. However, white light modulated by coating yellow fluorescent powder with LED blue light chips has relatively high luminous efficiency and simple preparation process. Therefore, luminescent materials excited by blue light have gradually become a trend. For light-emitting diodes, aluminum octahydroxyquinoline is the most typical organic light-emi...
