Abstract:

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 ∼90 nm in size can be readily obtained at 900 °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 5D07F2 electric dipole transition. The excellent luminescence properties make it possible as a good candidate for PDP application.
