ABSTRACTZnO nanofibers doped with Ga, In and Er metals have been fabricated by electrospinning technique. The diameter of the fibers was in the range of 0.5-2 μm and the length can be up to several feet. After spinning fabrication step the samples were dried out and annealed at 900 °C in air. Room temperature photoluminescence (PL) spectra measured for undoped and In- and Ga-doped ZnO fiber samples exhibit only a strong near band edge (NBE) emission at ∼380 nm with very weak green band at 525 nm. In contrary, the PL spectrum of Er-doped ZnO fibers shows a very weak NBE and strong green emission band at ∼550 nm at 300 K. The electrospinning mechanism used for the fabrication of nanofibers was found to be productive, simple and easy to implement disregarding of the doping type and concentration.

We have obtained Er-doped ZnO thin film in a micropattern of reverse trapezoids processed on Si substrate by sputtering and ultrafine polishing techniques. Near-infrared light emission was detected successfully from the thin film filling a single micropit with 10 μm square. Transmission electron microscopy (TEM) observation showed epitaxial growth of ZnO crystals along the curvature of the micropit.
