  • Method for producing luminescent nanoparticles
    Patent number: 11365349
    Abstract: The present invention relates to a method for producing luminescent nanoparticles wherein particle size of the nanoparticles is controlled. The method of the present invention includes admixing two or more rare earth metal salts in a first solvent and an organic oil to form a reaction mixture, and subjecting the reaction mixture to an inert gas so that flow rate of the inert gas is at least 2-5 L/h and pressure in the reaction vessel is at least 50 Pa over atmospheric pressure, preferably 50-80 Pa over atmospheric pressure.
    Type: Grant
    Filed: March 10, 2017
    Date of Patent: June 21, 2022
    Assignee: KAIVOGEN OY
