文摘

Well-crystallized Eu3+-doped perovskite materials CaTiO3 with a series of Ca/Ti ratio were synthesized. The luminescence of Eu3+ in all samples does not witness a significant change under different wavelength excitation. It is more likely for Eu3+ to occupy the Ca2+ site and the occupancy of Eu3+ ions is independent of Ca/Ti ratio.
