PREPARATION METHODS FOR FLUORESCENT NANOPARTICLES DOPED WITH RARE EARTH AND THEIR SOLUTION, AND SYSTEM THEREOF

摘要

Preparation methods for fluorescent nanoparticles doped with rare earth and their solution, and system thereof are provided. The said methods include the following steps: mixing cation source compounds, anion source compounds and at least one solvent for controlling crystal growth of the said fluorescent nanoparticles doped with rare earth to form a mixing solution; and keeping the said mixing solution in micro-reactor at a predetermined temperature for predetermined time to obtain the solution of the fluorescent nanoparticles doped with rare earth, wherein the said micro-reactor includes one micro-mixing-device and one micro-heat-exchanger. The micro-mixing-device is used for mixing the mixing solution continuously and the micro-heat-exchanger is used for adjusting the temperature of the micro-reactor to the predetermined temperature. The fluorescent nanoparticles doped with rare earth have uniform size, high crystallinity and high stability of product quality.
