Fabrication and Properties of Zinc Silicate Long Afterglow Phosphors

Article Preview

Abstract:

Zinc silicate-based (Zn2SiO4:Eu3+) long afterglow phosphors were fabricated by combustion synthesis and annealing method. The effects of different Zn sources, annealing temperature, Eu3+ additive on the properties of the combustion products have been studied. The results show that, the product is white with ZnO as zinc source while that from Zn(NO3)26H2O is slightly yellow. At higher annealing temperature, the sample is purer. Small amount of Eu2O3 additive did not change the phase composition. The fluorescence spectroscopy shows that, the emission peak of the sample with Eu3+ additive located at 620nm.
