Phosphor and Method for Producing Same, and Light-Emitting Device Using Same and Method for Manufacturing Such Device |
摘要 |
When a phosphor for ultraviolet excitation or visible light excitation is excited by light having wavelengths in a range of 100 to 500 nm and emission colors of the phosphor are represented by xy coordinates, the phosphor has a difference between a maximum value and a minimum value of x coordinates and a difference between a maximum value and a minimum value of y coordinates which are respectively 0.020 or less. A light-emitting device includes a light-emitting part which contains at least such a phosphor. The light-emitting part emits visible light when irradiated with ultraviolet or visible light emitted from an excitation source.
