Low temperature synthesis and luminescent properties of Ca2SnO4 : Eu 3+

摘要：

A novel red emitting phosphor, Ca2SnO4 : Eu 3+, was prepared by the low temperature solid state reaction. X-ray powder diffraction (XRD) analysis confirmed the formation of Ca2SnO4 : Eu 3+. Scanning electron-microscopy (SEM) observation indicated a narrow size distri-bution of about 500 nm for the particles with spherical shape. Under 396 nm excitation, the Ca2SnO4 : Eu 3+phosphor exhibits novel red emission at about 613 nm which is assigned to the 5D0 →7F2 electric - dipole transition. Furthermore, the emission transition 5D0 →7F2 has been found to be more prominent over the normal orange emission transition 5D0 →7F1.
