WHITE LIGHT-EMITTING DIODE (LED) AND PHOSPHOR FOR WHITE LED

摘要

PROBLEM TO BE SOLVED: To provide a high-luminance white light-emitting diode (LED) using an ultraviolet light-emitting diode and to provide a phosphor for the high-luminance white light-emitting element using the ultraviolet light-emitting diode.

SOLUTION: The white light-emitting diode uses a blue light-emitting inorganic phosphor containing both Ba and Mg, both Ca and S, or both Ca and Sr; a green light-emitting inorganic phosphor containing both Ba and Si or both Zn and Ge; and a red light-emitting inorganic phosphor containing both Ca and S, both Mg and Ge, or both K and W.
