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 synthe
