Abstract | A series of nanocrystallines MSO4:xSm3+ M = Ca, Sr, Ba; x = 0.001 - 0.005) were prepared by a co-precipitation method. Their crystal structures and fluorescence with and without γ-ray irradiation are compared. It was found that their crystal structures have not changed and their lattice parameters of nanocrystals both with and without γ-ray irradiation were increased with the augmentation of the content of doped Sm3+; however, their lattice parameters of the same nanocrystals with irradiation become smaller than that without irradiation. The characteristics emissions of both Sm3+ ion and Sm2+ ion are observed in the same nanocrystals after γ-ray irradiation. The differences in their crystal structures and luminescent properties are also discussed. |
