Abstract
ZnO seed layers were deposited on a quartz substrate using the sol-gel method, and In-doped ZnO (IZO) nanorods with different In concentrations ranging from 0 to 2.0 at. % were grown on the ZnO seed layers by the hydrothermal method. The structural and optical properties of the ZnO and IZO nanorods were investigated using field-emission scanning electron microscopy, x-ray diffraction (XRD), and photoluminescence (PL). The ZnO and IZO nanorods grew well aligned on the surface of the quartz substrates. From the XRD data, it can be seen that the In doping is responsible for the distortion of the ZnO lattice. The PL spectra show near-band-edge emission and deep-level emission, and they also show that In doping significantly affects the PL properties of ZnO nanorods.
