Figure 1From: Integrated nanophotonic hubs based on ZnO-Tb(OH)3/SiO2 nanocomposites Fabrication of ZnO-Tb(OH) 3 /SiO 2 composites. (a) XRD pattern and (b) SEM image of an initially grown ZnO nanotip on a Tb(OH)3/SiO2 nanosphere. Inset is the TEM image of a single Tb(OH)3/SiO2 nanoparticle of 250 nm with the scale bar of 50 nm. (c) SEM image of ZnO nanotip composites, sea urchin-type.Back to article page
