Abstract:
The present invention provides a nano particle phosphor with superior luminous characteristic formed using nitride semiconductor material, a method of manufacturing the phosphor with high production yield, and a light emitting device using the phosphor. The phosphor is formed of a columnar crystal having a diameter of at most 3 nm, a light emitting region and a light absorbing region are defined in the columnar crystal, and the light emitting region and the light absorbing region are adjacent to each other along a longitudinal direction of the columnar crystal.
