This paper reports that ZnSnO nanofibers (ZSNFs) were synthesized by thermal oxidation of ZnSn alloys. ZnSn alloys were prepared by cold press and sintering (powder metallurgy). The structure and optical properties were characterized by X-ray diffraction (XRD), micro-Raman scattering technology, field emission scanning electron microscopy (FESEM) and photoluminescence (PL) spectrum. The micro-Raman scattering spectra of ZSNFs show four Raman peaks at 574, 1156, 1729 and 2330 cm(-1). The diameter and length of ZSNFs are about 50nm and 60 mu m, respectively. The room temperature PL spectra of ZSNFs shows the near-band-edge emission at similar to 391nm and a broad green emission at similar to 493nm.
