Phosphor, phosphor manufacturing method, and white light emitting device

摘要

Provided are a phosphor, a phosphor manufacturing method, and a white light emitting device. The phosphor is represented as a chemical formula of aMO-bAlN-cSi3N4, which uses light having a peak wavelength in a wavelength band of about 350 nm to about 480 nm as an excitation source to emit visible light having a peak wavelength in a wavelength band of about 480 nm to about 680 nm. (where M is one selected from alkaline earth metals (0.2@a/(a+b)@0.9, 0.05@b(b+c)@0.85, 0.4@c/(c+a)@0.9)).
