Raveearth multi-element compounding material light conversion agent with ecological and phycological characteristics and preparation process thereof

Abstract

The present invention relates to a rare earth multi-component coordination compound light-converting agent with ecological and physiological characteristics, its mole ratio is as follows: rare earth 1, organic ligand 0-6, organosilicon surfactant (A) 0-6, and solvent 3-10, in which the rare earth ion is Eu(3+), which is provided by nitrate and hydrochloride of trivalent europium, and the chemicalstructure formula for its organosilicon surfactant is (RO)3SiR1N+R2R3R4X-. Its organic ligand is alpha-thenoyltrifluoroacetone (TTA), triphenyloxyphosphine (TPPO) or its two-component coordination compound. Its applicable liquid solvent is methylbenzene, dimethyl benzene, methyl alcohol, cyclohexane, ethyl alcohol, isopropanol, methyl-sulfoxide or their mixture, and its solid solvent is silicone.

Description

technical field The invention provides a light-changing agent with ecological and physiological characteristics, especially a light-changing agent emitting blue light or red light or a mixed light-changing agent emitting blue light and red light at the same time, and a preparation method of the light-changing agent . This kind of light conversion agent has the special function of efficiently converting ultraviolet light in different wavelength bands into light and the most powerful blue light, red light or blue-red mixed light band. Background technique From an ecological point of view, sunlight contains ultraviolet rays in three bands: UV-A (320-390nm), UV-B (280-320nm), and UV-C (below 280nm). It is harmful light. The present invention synthesizes a class of Eu-organic multi-component complexes, which are characterized in that they can absorb all the ultraviolet light (UV-A, UV-B, UV-C) in the whole band and convert them into visible light that is harmless to living bod...

AI Technical Summary

Problems solved by technology

However, the existing light conversion agents have the following problems, which have significantly affected their application (economic development) in production practice: the fluorescent materials that convert harmful ultraviolet light into blue light or blue-red mixed light are scarce; Low conversion luminous efficiency
