The Zn1−xMgxO (x=0%, 2% and 5%) microtubes have been successfully synthesized via a microwave heating method. The as synthesized microtubes were carefully investigated. Field emission scanning electron microscope (FE-SEM) showed that all the microtubes exhibit an exact hexagonal hollow structure with smooth surfaces and straight characteristics throughout their whole lengths. UV–Vis measurement indicates...
This paper is concerned with Cu-doped nano-crystal ZnO thin films deposited on Si (100) substrates and prepared by sol–gel method. The analyses of these thin film samples with X-ray diffraction (XRD) and scanning electron microscopy (SEM) reveal that these thin films have polycrystalline wurtzite structures and high c-axis preferred orientation. The photoluminescence (PL) spectra of thin film samples...
