Novel porous CaSnO3:Eu3+ and Ca2SnO4:Eu3+ phosphors by co-precipitation synthesis and postannealing approach: A general route to alkaline-earth stannates
چکیده انگلیسی

Novel porous CaSnO3:Eu3+ and Ca2SnO4:Eu3+ phosphors have been successfully prepared by postannealing the corresponding precursors at elevated temperatures. The precursors were firstly obtained by co-precipitation method at room temperature. The as-prepared phosphors were well characterized by means of X-ray powder diffraction (XRPD) and field emission scanning electron microscopy (FESEM). The photoluminescent excitation and emission spectra illustrate the red-emitting nature of CaSnO3:Eu3+ and Ca2SnO4:Eu3+ phosphors. Moreover, CaSnO3:Eu3+ phosphors with various shapes were obtained by introducing certain kinds of additives. Importantly, this facile synthetic method can be readily extended to prepare many other alkaline-earth stannates including BaSnO3:Eu3+, Ba2SnO4:Eu3+, SrSnO3:Eu3+, and Sr2SnO4:Eu3+ phosphors.
