PROBLEM TO BE SOLVED: To provide a brightness control method of wavelength conversion nano-particles and the wavelength conversion nano-particles, capable of further enhancing emission brightness of manufactured wavelength conversion-nano particles in a solution.SOLUTION: In a manufacturing process of wavelength conversion nano-particles, emission brightness higher than before can be achieved by treating them at a high pressure (for example, 607.95 kPa) and a high temperature (for example, 200°C) after a pH is adjusted to a pH of 10.5 higher than before. After manufacturing of the wavelength conversion nano-particles, excess Mn can be deposited by supplying oxygen having a concentration less than that of the atmosphere to an aqueous solution having dispersed wavelength conversion nano-particles to further enhance emission brightness of the wavelength conversion nano-particles. |
