Tb doped ZnO micro- and nanostructures have been grown by a catalyst free vapor-solid method. Luminescence properties and waveguiding behavior of the diverse nanostructures have been investigated by cathodoluminescence (CL) and micro-photoluminescence (mu-PL). Luminescence spectra of nanobelts and nanowires show the Tb3+ emission lines. Efficient waveguiding behavior has been observed for both ZnO and Tb3+ luminescence bands in the microwires. Optical resonant modes have been also observed in nanotriangles and tapered nanowires opening the possibility of their use in a wide variety of optical devices.
