An analysis is presented of optical absorption and emission in semiconducting, metallic, and mixed core-shell nanowires are considered theoretically. Due to image forces caused by the difference in dielectric constants between nanowires and their environment, absorption and emission coefficients are different for light polarized parallel or perpendicular to the nanowire axis. As a result, the intensity and spectra of absorption, luminescence, luminescence excitation, and photoconductivity in…
