Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a novel aluminate compound phosphor and a method for preparing the same.SOLUTION: The chemical properties of the aluminate compound phosphor can be improved by replacing part of Al/F elements with Si/O elements. The aluminate compound phosphor is represented by the general formula: CaSrBaAlSiOFR, wherein R is at least one selected from lanthanide metals. In addition, the light-emitting property of the phosphor is controlled by replacing part of the Al/F elements with the Si/O elements to finely adjust the composition and modifying the abundance ratio of each valence of the lanthanide metal contained in the phosphor.
