摘要：

Ultrawide ZnSe nanoribbons are synthesized by the simple thermal evaporation. The microstructure of ZnSe nanoribbons is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), high-resolution TEM (HRTEM), photoluminescence (PL) and Raman spectrum. It is found that the strong emission near the band gap of ZnSe centered at 460 nm is obtained in these nanoribbons. More importantly, ZnSe nanoribbons can act as lasing emitting optical cavities. Raman studies indicate that the longitudinal optic (LO) and transverse optic (TO) phonon confinements of the ZnSe nanoribbons shift to lower frequency. © 2010 Tianjin University of Technology and Springer-Verlag Berlin Heidelberg.
