High Color Rendering Index and High Thermal Characteristics of Red Nitride Phosphors

摘要

The high color rendering index (CRI) and high thermal properties of the red nitride phosphor are proposed in the invention. The phosphor would keep the original crystal phase and reduce the change of crystal volume by replacing different atoms. In addition, the red nitride phosphor can be excited by an incident light with wavelength ranging from 370 nm to 470 nm, and that shows the red phosphor of the present invention can be applied in white light emitting diodes. Moreover, the red nitride phosphor proposed by the present invention includes the potential application in main peak modulation and FWHM adjustment, and would be helpful to improve the thermal stability problem of white light emitting diodes.
