Synthesizing upconverting nanoparticles includes heating a precursor solution comprising one or more rare earth salts, an alkali metal salt or alkaline earth salt, and a solvent comprising a plasticizer in a microwave reactor to yield a product mixture, and cooling the product mixture to yield the upconverting nanoparticles. Core-shell upconverting nanoparticles are synthesized by combining the upconverting nanoparticles with a precursor solution comprising one or more rare earth salts, an alkali metal salt or alkaline earth salt, and a solvent comprising a plasticizer to yield a nanoparticle mixture, heating the nanoparticle mixture in a microwave reactor to yield a product mixture, and cooling the product mixture to yield the core-shell upconverting nanoparticles.

A closed-loop large-scale preparation method of fluoride nanomaterial is disclosed, comprising the following steps: dissolving initial raw material into water-soluble salt by using volatile acid; evaporating the remaining acid under reduced pressure and recovering; then, adding oily organic matter with high boiling point to continue to evaporate the combined volatile acid under reduced pressure; adding an oil-soluble fluorine source to the generated oil-soluble salt; increasing the reaction temperature to increase the crystallinity of the fluoride; after cooling, separating and recovering the product and the oily organic matter; and repeating the process to realize large-scale preparation. The method uses the closed-loop process flow, does not discharge waste, and has high device yield per unit volume, low production cost and low specified asset investment. The product has the characteristics of uniform particle size and good dispersibility. The method is a user-friendly and environment-friendly large-scale preparation method of the fluoride nanoparticles.
