Disclosed are photoluminescent tiles containing photoluminescent materials, and manufacturing methods thereof. A tile is filled or glazed with photoluminescent glaze powder including photoluminescent phosphor comprising a MAl2O4 compound (M: metal) as a matrix, and then baked, thereby obtaining the photoluminescent tiles. Since the photoluminescent tiles can be manufactured via a dry process, the manufacturing method is convenient and enables mass production via process automation. Additionally, the photoluminescent tiles of the present invention can be baked at a high temperature, and do not have degradations, such as fine cracks on the photoluminescent materials.
