摘要：

Nanometer-scale SnO2 particles have been synthesized by a simple coprecipitation method. X-ray diffraction analysis shows that the diameter of the particles is 2.6 nm after heat treatment at 400 degreesC for 2 h. The UV-visible absorptive spectra and photoluminescence spectra have been used to study the luminescence character of Eu3+ ions. The characteristic emission and concentration quenching of Eu3+ ions can be observed. The results also reveal that the Eu3+ ions can be situated not only at the surface of the SnO2 nanoparticles but also in the host lattice, though the relative quantity is very small.
