ZnO microrods were grown by laser assisted flow deposition technique in order to study their luminescence behaviour in the near band edge spectral region. Transmission electron microscopy analysis put in evidence the high crystallinity degree and microrod's compositional homogeneity. Photoluminescence revealed a dominant 3.31 eV emission. The correlation between this emission and the presence o...

Vertically aligned N-doped ZnO microrods with a hexagonal symmetry were fabricated via the chemical vapor transport with abundant N2O as both O and N precursors. We have demonstrated the suppression of the zinc interstitial-related shallow donor defects and have identified the zinc vacancy-related shallow and deep acceptor states by temperature variable photoluminescence in O-rich growth enviro...

This project’s goal was to mimic the Saharan silver ant’s micro-hair arrays by creating a solar heat reflecting membrane with parallel-aligned Al-ZnO microrods using Mayer rod coating method. The synthesis of carried out hydrothermal then produced mixing liquid silicone rubber and spreading mixture into shape rod. dragging microrod, confined between polypropylene film, induces partial alignment...

One-dimensional single crystal incorporating functional nanoparticles of other materials could be an interesting platform for various applications. We studied the encapsulation of nanoparticles into single-crystal ZnO nanorods by exploiting the crystal growth of ZnO in aqueous solution. Two types of nanodiamonds with mean diameters of 10 nm and 40 nm, respectively, and polymer nanobeads with si...

Fluorescent nano-/microrods of the polyoxometalate (POM) K4H[Eu(α-SiW11O39)(H2O)2] · 17H2O were obtained in aqueous solution by a conventional synthesis method. The nano-/microrods have been characterized by elemental analysis and FT-IR, UV/Vis, and TG-DTA data, and their morphology was examined by ESEM-FEG, showing that the average ratio of diameter to length is 1 : 20. The obtained nano-/micr...
