| description | <p>Abstract</p><p>Silica xerogels containing Sm<sup>3+</sup>ions and SnO<sub>2</sub>nanocrystals were prepared in a sol–gel process. The image of transmission electron microscopy (TEM) shows that the SnO<sub>2</sub>nanocrystals are dispersed in the silica matrix. The X-ray diffraction (XRD) of the sample confirms the tetragonal phase of SnO<sub>2</sub>. The xerogels containing SnO<sub>2</sub>nanocrystals and Sm<sup>3+</sup>ions display the characteristic emission of Sm<sup>3+</sup>ions (<sup>4</sup>G<sub>5/2 </sub>→ <sup>6</sup>H<sub><it>J</it></sub>(<it>J</it> = 5/2, 7/2, 9/2)) at the excitation of 335 nm which energy corresponds to the energy gap of the SnO<sub>2</sub>nanocrystals, while no emission of Sm<sup>3+</sup>ions can be observed for the samples containing Sm<sup>3+</sup>ions. The enhancement of the Sm<sup>3+</sup>emission is probably due to the energy transfer from SnO<sub>2</sub>nanocrystals to Sm<sup>3+</sup>ions.</p> |
