Attenuation coefficient measurements for the propagation of
bandedge luminescence are made on individual ZnO nanowires by
combining the localized excitation capability of a scanning electron
microscope (SEM) with near-field scanning optical microscopy (NSOM) to
record the distribution and intensity of wave-guided emission.
Measurements were made for individual nanostructures with triangular
cross-sections ranging in diameter from 680 to 2300 nm. The effective
attenuation coefficient shows an inverse dependence on nanowire diameter
(dà à ¢ 1), indicating scattering losses due to non-ideal waveguiding behavior.
