Embodiment Construction

[0017] EuCl 3 ·6H 2 Preparation of O: Eu with a purity of 99.99% 2 o 3 Dissolve in 1:1 hydrochloric acid, heat and evaporate excess hydrochloric acid in the solution on an electric furnace until a little crystal film forms on the liquid surface, after cooling, suction filter and dry to obtain EuCl 3 ·6H 2 Crystals of O, spare.

[0018]

[0019] Preparation of binary complexes: EuCl 3 ·H 2 O and 2,2'-biphenyldicarboxylic acid were respectively dissolved in water and ethanol at a molar ratio of 2:3, and then the two were mixed, and the mixed solution was adjusted to pH 5-7 with sodium hydroxide, and a large amount of precipitate was obtained. It is a binary complex of europium-2,2'-biphenyldicarboxylic acid, which is filtered by suction and dried for later use.

[0020]

[0021] Preparation of the ternary complex: Put the binary complex obtained in the previous step and 1,10-phenanthroline in a molar ratio of 1:2 into a high-temperature reaction kettle, inje...

Abstract

The invention discloses an optical transferring material, in particular an one dimensional u-tri (2,2'-biphenylece-0, 0') dihydrate di (1,10-phenanthrdine-N,N') bis europium (III) monohydrate and its preparation, which is mainly used in the field of agricultural film and laser emitter.

Description

technical field [0001] The invention relates to a light conversion material, specifically a one-dimensional linear μ-tris(2,2-biphenyl dicarboxylic acid-O,O') dihydrate bis(1,10-phenanthroline-N, N') Dieuropium (III) monohydrate complex and its preparation method are usually used in agricultural films, laser emitters and the like. Background technique [0002] Rare earth europium organic coordination compounds are a class of light conversion materials that are currently being studied at home and abroad. The remarkable characteristic of this kind of light-converting material is that it can convert ultraviolet light in sunlight into red-orange light, and promote photosynthesis of plants. About light conversion materials As early as 1967, Japan's "Agricultural Light Selective Utilization Technology Research Association" had carried out comprehensive research on greenhouse agricultural light energy utilization technology. In the 1990s, Mitsui East Asia Chemical Co., Ltd. and BA...
