Sb-doped ZnO thin films with different values of Sb concentrations are deposited on glass substrate by using spin-coating technique. The influences of Sb doping content on the microstructural, photoluminescence and Raman properties of ZnO film are systematically investigated by X-ray diffraction (XRD), transmission spectrum, photoluminescence (PL) spectrum and Raman scattering spectrum. The results indicate that ZnO thin film doped with Sb exhibits a hexagonal wurtzite structure with preferred c-axis orientation. The strong violet emission peak located at 3.11 eV is observed in the Sb-doped ZnO thin film by photoluminescence. Conbining the Raman scattering spectrum with photoluminescence, it is concluded that the strong violet emission peak related to SbZn-O complex defect in ZnO:Sb film.

Infrared And Raman Spectroscopy

We report both infrared transmission and Raman scattering results on the new superconducting Bi-Sr-Ca-Cu-O system. Because of its layered structure along c axis, some very thin and transparent slices have been got. In the infrared spectrum there is an absorption band around 500cm−1 with a width of about 300cm−1, and a vibrational mode at 840cm−1, higher frequency than those of phonon modes in Y-Ba-Cu-O system, has also been observed. The Raman scattering spectrum shows similar results, but the scattering signals are very weak because of the strong absorption in visible of this system.
