Problems solved by technology

However, a large number of studies have found that after the organic ligands with good luminescent properties are coordinated with metal ions, the transition energy transfer efficiency is low when the charge is transferred to the central metal ion, resulting in energy loss. The weakening of fluorescence intensity affects the luminescent properties of fluorescent materials

Abstract

The invention provides a 4-hydroxycoumarin-containing cadmium-inserted fluorescent material and a synthesis method thereof, and relates to the field of fluorescent materials. The 4-hydroxycoumarin-containing cadmium-inserted fluorescent material has a molecular formula of {[Cd(4,4'-bpp)2(H2O)2].2(4-Hcm-).H2O}n, is a light yellow crystal, is synthesized by a solution method and has high purity. At a room temperature, the {[Cd(4,4'-bpp)2(H2O)2].2(4-Hcm-).H2O}n produces bright blue-fluorescence under the irradiation of ultraviolet rays, and has a quantum yield of 12% and strength obviously higher than strength of dissociative fluorescent molecules and a main metal organic framework. The synthesis method is a novel method, has simple processes, low equipment requirements and a low cost. The 4-hydroxycoumarin-containing cadmium-inserted fluorescent material is in a crystal state, has high purity, good heat stability and good regulation performances, can be used as a novel fluorescent material and can be used for manufacture of a fluorescent luminescent device.

Description
