long lasting luminescence powder and low melting glass powder were synthesized by high-temperature solid-state reaction respectively. Secondly

the two components were weighed in appropriate mass ratio and mixed homogeneously. Finally

the mixtures obtained were sintered at different temperature for 10 min. The afterglow properties were researched systemically. The effects of the amount of CaTiO

red long (afterglow) emission. There was a broad band from 350 nm to 550 nm in the excitation spectrum

which showed that the glass could absorb the energy from near ultraviolet to yellow green

so the samples could be excited by sun light and lamplight then emitte the red long lasting afterglow. When the mass proportion of glass powder and phosphors is within 95:5～80:20

the pure glass phase could be gained and excellent red long afterglow could be observed. The effects of the atmosphere and the fuse temperature on the luminescent property were studied. The samples prepared at 800℃ in air have better (luminescent) characteristic.
