چکیده
A double‐pulsed laser ablation (DPLA) method has been used to synthesize crystalline boron nanorods (BNRs), nanowires (BNWs), and bamboo‐like nanotubes (BBNTs) from bulk (BKB). q‐switched Nd: YAG operating at the first second harmonic wavelengths with 1064 532 nm is ablate a solid composite target doped 1% Ni Co in tube furnace flowing argon gas. Boron nanostructures form of BNRs, BNWs, BBNTs are condensed hot laser‐induced plasma plume temperatures 800, 900, 1000 °C. The morphology chemical optical nature identified X‐ray diffraction, electron microscopy, energy‐dispersive spectroscopy, Raman, UV–vis, photoluminescence (PL) spectroscopies. results confirm crystallinity phase purity boron‐nanomaterials that they preferentially grown c‐axis direction α‐boron. as‐synthesized observed have lengths 0.2–1.5 μm widths between 10 100 nm, show respective PL resonance emission peaks 330, 331, 333 electrical conductivities 312, 313, 324 S cm −1 room temperature which higher than conductivity BKB.

Recently, branched and star-shaped gold nanoparticles have received significant attention for their unique optical and electronic properties, but most examples of such nanoparticles have a zero-dimensional shape with varying numbers of branches coming from a quasi-spherical core. This report details the first examples of higher-order penta-branched gold particles including rod-, wire-, and plat...
متن کاملCatalyst-Free Synthesis and Characterization of Metastable Boron Carbide Nanowires
Catalyst-free growth of boron carbide nanowires is achieved by pyrolysis of diborane and methane at 650–750 -C and around 500 mTorr in a quartz tube furnace. Electron-diffraction analysis using a novel diffraction-scanning transmission electron microscopy (D-STEM) technique indicates that the crystalline nanowires are single-crystal orthorhombic boron carbide. TEM images show that the nanowires...
