Abstract
Pure and Sn(IV) doped ZnO 1D nanostructures were synthesized by a convenient thermal evaporation method. SEM, EDS, XRD and TEM were used to examine the morphology, composition, phase structure and crystallinity of as-prepared ZnO samples. Raman spectra were used to confirm Sn(IV) doped into ZnO lattice effectively. The Raman spectra of doped ZnO 1D nanostructures also show strong electron-phonon coupling. PL spectra were used to investigate the optical properties of as-prepared samples, which show strong UV emission in pure ZnO while there is dominant green emission in doped ZnO. More interesting, the green emission contains discrete multi-sub-bands because of electron-phonon coupling and optical cavity effect in the doped 1D nanostructures.
