Problems solved by technology

[0003] Under the prior art, lead halide luminescent material (C 3 h 8 N 6 )PbC l4 , however, the extreme toxicity of lead goes against the concept of green chemistry and sustainable development
Solid solution luminescent materials can be synthesized by coprecipitation method (C 10 h 16 N) 2 Zn 1-x mn x Br 4 , however, (C 10 h 16 N) 2 Zn 1-x mn x Br 4 There is only one metal ion Mn in solid solution 2+ glowing while Zn 2+ Does not emit light, that is, there is only one luminous center, and the emission color cannot be adjusted, which is limited in practical applications

The solid solution luminescent material is friendly to the environment. The light color from blue light emission to green light emission can be adjusted.

Description

Technical field [0001] The present invention relates to the field of luminescent materials, and more particularly to a solid solution luminescent material based on cadmium and manganese and a preparation method thereof. Background technique [0002] Metal halide calcium titanium ore has become a functional material including a photovoltaic cell, a light emitting diode, a photodetector, and the like due to its excellent photoelectric properties and a simple preparation process. Among them, the organic-inorganic hybrid halide luminescent materials have attracted the extensive attention of researchers due to excellent photoelectric properties and rich structural characteristics. In recent years, researchers have mainly placed the research of halide luminescent materials in the primary and calcium ore. [0003] Under the prior art, a lead-emitting material can be synthesized by using a slow solvent volatile (C 3 Hide 8 N 6 ) PBC l4 However, the risk of lead has violated the concept o...
