Abstract X-ray diffraction (XRD) and Photoluminescence (PL) measurements were performed in order to investigate the tunable color emission in a Ba 1− x Sr x Y 2 S 4 : Eu 2+ phosphor. The results of the XRD measurements showed that the Ba 1− x Sr x Y 2 S 4 : Eu 2+ is crystallized with the orthorhombic structure, and those of the PL measurements showed that the PL peak observed in Ba 1− x Sr x Y 2 S 4 : Eu 2+ had a red-shift behavior as a Sr concentration increased. These results indicate that the tuning range of the emission color is approximately between 600 and 640 nm in the Ba 1− x Sr x Y 2 S 4 : Eu 2+ phosphor by changing the Sr composition.
