Description

technical field

[0001] The invention relates to the technical field of fluorescent substances, in particular to a fluorescent substance based on an amino acid deep eutectic solvent and a preparation method thereof. Background technique

[0002] At present, in the preparation process of fluorescent substances, a large amount of volatile and highly polluting organic solvents are used, which is not friendly to the environment. Traditional fluorescent substances generally use phosphor powder systems. At present, the systems that can be practically applied mainly include: yttrium aluminum garnet oxide, alkaline earth metal silicon (aluminum) salt, nitrogen (nitrogen oxide) compound, sulfur (sulfur oxide) compound, etc., there are Low efficiency, poor thermal stability, and difficulty in achieving uniform particle size of phosphors. In addition, the preparation process of phosphors is generally high temperature, which requires a lot of energy and high cost. Therefore, it is of gr...
