METHOD FOR SYNTHESIZING Pr AND Mn CODOPED ZnS NANOPARTICLES AS A WHITELIGHT EMITTING MATERIAL AND METHOD FOR ENHANCING LUMINESCENCE THEREOF

摘要

The present invention relates to a method for producing a Pr, Mn-doped ZnS nanoparticle white light material by a liquid colloid method and a method of increasing the luminous efficiency of a white light material by an optical method.;    The preparation method according to the present invention synthesizes ZnS nanoparticles by chemical method in solution, and synthesizes doped ZnS nanoparticles by mixing reactants of Pr and Mn in the synthesis process and the measurement of optical properties using 325nm UV laser and the same An annealing process by an optical method using a light source.;According to the present invention, ZnS nanoparticles that can be applied to a white light emitting device by doping Pr and Mn together in ZnS can be synthesized by a simple liquid chemical method, and the luminous efficiency can be increased through an annealing process by an optical method.;ZnS nanoparticles, doping, optical annealing, white light emitting material, semiconductor light emitting material
