摘要
In this paper, CaSnO3:Eu3+ nanocrystals were prepared by hydrothermal synthesis method. The influence of different molar ratio of Ca:Sn on structure of CaSnO3:Eu3+ was investigated by using X-ray powder diffraction (XRD). Well-crystallized and phase-pure CaSnO3:Eu3+ particles of similar to 90 nm in size can be readily obtained at 900 degrees C. Furthermore, photoluminescence characterization of the Eu3+-doped CaSnO3 nanocrystals was performed and discussed. The emission peak situated at 618 nm showing prominent and bright red light is due to the D-5(0)-F-7(2) electric dipole transition. The excellent luminescence properties make it possible as a good candidate for PDP application.
