ZnO nano-rods synthesized by nano-particle-assisted pulsed-laser deposition

Highly transparent and reproducible nanocrystalline ZnO and AZO thin films grown by room temperature pulsed-laser deposition on flexible Zeonor plastic substrates

“…The next ablation plume will then build up another patchy layer of similarly shaped nanoparticles and so on. In the case of a high-temperature (and possibly crystalline) substrate, the initial nanoclusters will diffuse rapidly forming a wetting nucleation layer onto which crystalline ZnO nanorods can subsequently grow in a 3D growth mode [42,44]. Relevant to the present work are the fundamental aspects of the synthesis of silicon nanoclusters by conventional PLD discussed by Marine et al [43] and the work by Jensen [45] on the growth of nanostructures by cluster deposition.…”

Laser micro- and nanofabrication of biomaterials

“…Okada et al fabricated ∼ 120 nm ZnO nanorods using a catalystfree nanoparticle assisted pulsed laser deposition approach. 91 Optical pumping of the ZnO nanorods at 388 nm was used to obtain stimulated emission. In subsequent work, Okada et al used laser ablation in a high-temperature argon background gas to prepare ZnO nanorod structures with unusual geometries, including nanowire pig-tailed ZnO nanorods and ZnO nanocones.…”

A General Self-Propagating High-Temperature Synthesis Method for Fast and Easy Preparation of Metal Oxide Nanostructures from Low Melting Point Metals

“…Commonly employed methods for the preparation of SnO 2 nanowires or nanoparticles include gas-reaction, 10,11 thermal evaporation, 12,13 chemical vapor deposition (CVD), [14][15][16] carbothermal reduction, calcination process, 20 polymeric sol-gel process, 21 thermal decomposition process, 22,23 etc. In a similar vein, the synthesis of ZnO nanorods or nanoparticles is often achieved through thermal evaporation, 24 laser ablation, 25,26 hydrothermal method, 27 solvothermal method, 28,29 sonication, 30 sol-gel process, 31,32 electrohydrodynamics atomization (EHDA), 33 sedimentation method, 34,35 microwave method, 36 solid-state reaction, 37 or thermal decomposition process. 38 While di®erent methods used to prepare Al 2 O 3 nanoparticles usually involve four steps: calcining, sieving, washing and stoving.…”

“…And some other methods, for instance, calcination process, sol-gel process, thermal decomposition process, hydrothermal method, solvothermal method, sonication, EHDA, and sedimentation method, are low yield or low e±ciency, and need complex processes and rich operational experience, and also usually result in the formation of undesired side product. [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] As the development of nanotechnology, researches for new environmentally friendly preparation methods are signi¯cant in nanomaterials synthesis area, especially for the commercial production of nanomaterials. Self-propagating High-temperature Synthesis (SHS) is an environmentally friendly method for materials synthesis relying on the reaction heat to maintain the reaction itself to obtain materials with designated composition or morphology from the¯nal reaction products.…”
