Conventional semiconductor particle phosphors have low dispersibility to a medium, and since they do not exhibit red, green and blue fluorescence, white emission cannot be obtained by mixing such colors. Synthesizing steps in the conventional methods for manufacturing such semiconductor particle phosphors are complicated, and especially control of the composition and particle diameter of semiconductor particles requires accurate control in synthesizing method. A group 13 nitride semiconductor particle phosphor (10) having a high dispersibility is provided by forming nanocrystalline particles (11) including bonding of a group 13 element and a nitride atom as the semiconductor particles and by coating the nanocrystalline particles (11) with a surface modified organic compound (12) having a molecular weight of 200-500, including hetero atoms. Furthermore, a simple method for manufacturing such group 13 nitride semiconductor particle phosphor (10) is also provided. ® KIPO & WIPO 2009
