The invention relates to a microfluidic-control preparation method for a
microsphere of a polymethylmethacrylate-coated
cadmium telluride (CdTe)
quantum dot, and relates to a preparation method for the
microsphere of a polymethylmethacrylate-coated CdTe
quantum dot. The microfluidic-control preparation method for the
microsphere of the polymethylmethacrylate-coated (CdTe)
quantum dot aims to solve the problems that the surface of the
quantum dot needs to be modified and the
quantum dot is easy to dissolve by the microsphere of the polymethylmethacrylate-coated CdTe
quantum dot by adopting a traditional preparation method for the microsphere of the polymethylmethacrylate-coated CdTe quantum dot. The method comprises the following steps: preparing a
sodium hydrogen telluride solution; preparing a CdTe quantum dot; preparing a
polymer solution; connecting a microfluidic-
control system; respectively putting the
polymer solution and
silicone oil into injectors A and B of the microfluidic-
control system; setting the propulsion speed of the injectors A and B; after starting, formed liquid beads flow into a
rotary evaporator; and curing and evaporating the
silicone oil to obtain the microsphere of the polymethylmethacrylate-coated CdTe quantum dot. In the microfluidic-control preparation method for the polymethylmethacrylate-coated CdTe quantum dot, the polymethylmethacrylate-coated CdTe quantum dot is selected, therefore,
fluorescence is stable, and the microsphere can be adjusted in size and can be used for field of fluorescent display and the like.
