英文摘要: The present paper reports the photoluminescence properties of nanocrytalline ASnO(3) (A = Ca, Sr and Ba) : 1% Eu phosphor synthesized by the Pechini-type sol-gel method. The powder was characterized by X-ray diffraction (XRD), UV-Vis absorption spectra, transmission electron microscopy (TEM) and photoluminescence measurements. The experimental results show that BaSnO3 has the ideal cubic peroskite structure, while SrSnO3 and CaSnO3 are both distorted from cubic symmetry by an octahedral tilting distortion. The difference of structure in induced the different spectral properties of ASnO3 1 Yo Eu. On the other hand, when A(2+) changes from Ca2+ to Ba2+, the luminescence intensity becomes weak. So CaSnO3 1 Yo Eu seems to be a good candidate for new phosphors.
