title: Structural and optical characterization of Zn(OH)2 and its composites with graphite oxides.
abstract: The optical properties of zinc (hydr)oxide and its porous composites with 2% and 5% graphite oxide (GO), thus forming ZnGO-2 and ZnGO-5, are investigated using reflectance spectroscopy and two-photon fluorescence (TPF) imaging. The bandgap energies for the Zn(OH)(2), ZnGO-2, and ZnGO-5 samples are determined to be in the range between 2.88 and 3.60 eV. The size of light-emitting regions (~from 4.5 to 45 μm) and pore size (~from 20 to 255 μm) are measured using the TPF imaging technique.
