METHOD OF PREPARING LANTHANIDE-DOPED KMNF3 NANOPARTICLES

摘要

The present invention discloses a method for preparing lanthanide-doped KMnF3 nanoparticles which exhibit single-band upconversion emission, comprising the steps of: mixing a manganese oleate precursor and at least one lanthanide precursor in a solvent comprising oleic acid to obtain a manganese oleate complex; mixing a solution of potassium fluoride (KF) with the manganese oleate complex to form a mixture; and heating the mixture to form the nanoparticles. There is also provided uses of the prepared nanoparticles.
