    Eu3+-doped Ca2SnO4 (solid solutions of Ca2-xEu2xSn1-xO4, 0≤x≥g0.3) and Eu3+ and Y3+-codoped Ca2SnO4 (Ca1.8Y0.2Eu0.2Sn0.8O4) were prepared by solid-state reaction at 1400°C in air, Rietveld analysis of the X-ray powder diffraction patterns revealed that Eu3+ replaced Ca2+ and Sn4+ in Eu3+-doped Ca 2SnO4, and that Eu3+ replaced Ca2+ and Y3+ replaced Sn4+ in Ca1.8Y 0.2EU0.2Sn0.8O4. Red luminescence at 616nm due to the electric dipole transition 5Do7F2 was observed in the photoluminescence (PL) spectra of Ca2-xEu2xSn1-xO4 and Ca 1.8Y0.2Eu0.2Sn0.8O4 at room temperature. The maximum PL intensity in the solid solutions of Ca 2-xEu2xSn1-xO4 was obtained for x = 0.1. The PL intensity of Ca1.8Y0.2Eu0.2 Sn 0.8O4 was 1.26 times greater than that of Ca 2-xEu2xSn1-xO4 with x = 0.1.
