Implement the embodiment of the present invention, have the advantages that：
Red quantum dot material and green quanta point material are mainly mixed and are filled in resistance to height by the technical solution of the embodiment of the present invention
The hydrogel microsphere of temperature, this preparation method can both keep the organic ligand structure of quantum dot surface not to be destroyed, and ensure it
Significant change will not occur for optical property, and can have the function that surface modification, both can keep quantum dot surface is organic to match
The stability of body, and its ph stability can be improved, quantum dot optical stability can be improved；
Hydrogel material of the present invention by adding in modification functional group in main chain, makes the thermal stability of hydrogel
The shortcomings that improving to 300 DEG C or more, improving previous hydrogel thermal sensitivity, makes the hydrogel fines for being mounted with quanta point material exist
Application in industrial process is improved；Meanwhile the quantum dot loaded in hydrogel fines will not be scattered in polar solvent or
In water, therefore clustering phenomena will not be occurred by solvent effect in film forming procedure, monodispersity is good；
In addition, in the method applied in the present invention, red quantum dot material and green quanta point material are mixed and be filled into one
In a hydrogel microsphere, the adjusting of mixed white light coloration can be realized by adjusting two amounts point rate of charge, without making respectively
The hydrogel microsphere of standby two kinds of colors is mixed again, method simple practical, suitable for large-scale industrial production.
