Blue fluorescent material and preparation method thereof

Abstract

The invention discloses a blue fluorescent material and a preparation method thereof. Sulfaquinoxaline and 4,4'-bipyridyl which have conjugate phi bonds and cadmium ions with optical activity are chemically reacted to prepare a sulfaquinoxaline cadmium compound with a certain spatial structure, and the molecular formula of the sulfaquinoxaline cadmium compound is C42H40CdN10O6S2, wherein M is equal to 957.36. The crystal system is monoclinic; the space group is C2 / c; and in the unit cell parameters, alpha is 90.00 degrees, beta is 126.005 degrees, and gamma is 90.00 degrees. Because of Cd (II) ions of rich optical activity and conjugate phi bonds, the compound fluorescent material is favorable for electron transition and energy transfer, has good photoelectric activity, shows good blue emitting performance, and can be used as a fluorescent material.

Description

technical field

[0001] The invention belongs to the field of material chemistry, and in particular relates to a cadmium compound blue fluorescent material and a preparation method thereof. Background technique

[0002] Fluorescent materials usually refer to the ability to absorb and store energy after receiving external energy and convert it into light energy in a dark place. It is calcined by metal (zinc, chromium) sulfide or rare earth oxide and trace active agent. . Colorless or light white, under the irradiation of ultraviolet light (200-400nm), according to the different types and contents of metals and activators in the pigment, it presents various colors of visible light (400-800nm).

[0003] With the advancement of science and technology, more and more researches on fluorescence have been carried out, and the application range of fluorescent substances has become wider and wider. In addition to being used as dyes, fluorescent substances are also widely used in orga...
