Abstract:
The wavelength conversion material includes a general formula (I) MmAaBbCcDdEe:ESxREy and satisfies a condition (II) that a proportion of D for the wavelength conversion material greater than or equal to 50%. M is selected from a group consisting of Ca, Sr and Ba. A is selected from a group consisting of elements Mg, Mn, Zn and Cd. B is selected from a group consisting of elements B, Al, Ga and In. C is selected from a group consisting of Si, Ge, Ti and Hf. D is selected from a group consisting of elements 0, S and Se. E is selected from a group consisting of elements N and P. ES is selected from a group consisting of divalent Eu, Sm and Yb. RE is selected from a group consisting of trivalent Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er and Tm.
