[Photoluminescence properties of A2SnO4 (A = Ca, Sr, Ba) : Eu nanocrystalline].
Nanosized A2SnO4 (A = Ca, Sr, Ba) : 1% Eu with diameters ranging from 50 to 100 nm were synthesized by complex sol-gel methods. The structures and spectral properties of A2SnO4 (A = Ca, Sr, Ba) : Eu were studied by using X-ray powder diffraction (XRD) and luminescence spectra. The experimental results show that Ca2SnO4 : 1% Eu exhibits bright red emission at about 615 nm under UV excitation, which makes it a possible good candidate for FED application. However Sr2SnO4 : 1% Eu and Ba2SnO4 : 1% Eu exhibit orange emission at about 590 nm because in these hosts Eu3+ ions occupy the symmetric sites.
