![]() Compared to the pure SnO 2 NWs, the PL spectrum of the core–shell nanostructures exhibits a stronger emission peak, which suggests potential applications in optoelectronics. The plasmonic coreshell nanomaterials were extensively used. The surface steps and defects induced by the lattice mismatch likely lead to improved photoluminescence (PL) performance for the yellow emission. As an ultrathin film preparation method, atomic layer deposition (ALD) has recently found. Atomically smooth surfaces are found for growth on the surfaces), the shell also derives an octagonal shape from the epitaxial growth, which was explained by a proposed model based on ALD kinetics. The growth behavior of the TiO 2 shells highly depends on the surface orientations and the geometrical shape of the core SnO 2 NW cross-section. ALD enables the fabrication of nanoparticle thin film on three-dimensional substrates (a 2D functional film on a 3D substrate), resulting in a. All characterizations, by X-ray diffraction, high-resolution transmission electron microscopy, selected area electron diffraction and Raman spectra, reveal that single crystalline rutile TiO 2 shells can be epitaxially grown on SnO 2 NWs with an atomically sharp interface at low temperature (250 ☌). In the present work, atomic layer deposition (ALD) was used to fabricate nanoparticle thin films of email protected and email protected in a core-shell structure on glassy carbon electrodes. Taking TiO 2/SnO 2 core–shell nanowires (NWs) as a model system, we systematically investigate the structure and the morphological evolution of this heterostructure synthesized by atomic layer deposition/ epitaxy ( ALD/ ALE).
