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 ~90nm 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 618nm showing prominent and bright red light is due to the 5D0-7F2 electric dipole transition. The excellent luminescence properties make it possible as a good candidate for PDP application.
