The luminous stone is prepared by using high temperature firing technology, and the influences of raw ma-terials, processing temperature, heating time, phosphor content on the properties of the luminous stone are studied under oxidizing conditions. The results show that when the raw materials is SrAl2O4:Eu2+, Dy3+ long afterglow phosphor of 100 mesh and low melting borate glass powder, phosphor content is 30%, temperature is 800°C, and heating time is 10min, the luminous stone has good apparent quality, strength and luminous performance. Using the luminous stone as concrete aggre-gate, the luminous exposed aggregate concrete can be prepared with functions of lighting and decoration.
