Abstract: A nano phosphor prepared by mixing a metal oxide nanoparticle and inorganic salt, a method of preparing the nano phosphor, and a display device including the nano phosphor. The method includes dissolving the inorganic salt in a solvent, adding the metal oxide nanoparticles to the solution, and annealing the resultant mixture, preferably under pressure. Such a process removes defects in the crystal structure of the nano phosphor, resulting in improved luminescent efficiency when incorporated into a display device.
