“…Reference data for particle size dependent saturation magnetization (all symbols in black color) are taken from Han et al [220], Morales et al [222], and de Montferrand et al [227], and finally the bulk reference value is taken from [228], page 993. Literature data of the diverse plasma synthesized F 2 O 3 nanoparticles (colored symbols) are taken from Table 7 (David et al [102,109], Nadeem et al [105], Vollath et al [107,108], Banerjee et al [114], Lei et al [115]). The bars herein are not error bars; they show the spread of indicated particle sizes.…”

Abstract:In this review, microwave plasma gas-phase synthesis of inorganic materials and material groups is discussed from the application-oriented perspective of a materials scientist: why and how microwave plasmas are applied for the synthesis of materials? First, key players in this research field will be identified, and a brief overview on publication history on this topic is given. The fundamental basics, necessary to understand the processes ongoing in particle synthesis-one of the main applications of microwave plasma processes-and the influence of the relevant experimental parameters on the resulting particles and their properties will be addressed. The benefit of using microwave plasma instead of conventional gas phase processes with respect to chemical reactivity and crystallite nucleation will be reviewed. The criteria, how to choose an appropriate precursor to synthesize a specific material with an intended application is discussed. A tabular overview on all type of materials synthesized in microwave plasmas and other plasma methods will be given, including relevant citations. Finally, property examples of three groups of nanomaterials synthesized with microwave plasma methods, bare Fe 2 O 3 nanoparticles, different core/shell ceramic/organic shell nanoparticles, and Sn-based nanocomposites, will be described exemplarily, comprising perspectives of applications.

“…This is because wet chemical processes involve low temperatures. In contrast to wet chemical processes, thermal plasma-based ones involve the evaporation of the constituent metals at temperatures higher than 10,000 K, followed by the rapid condensation of the gas phases [9][10][11][12][13]. Thermal plasma-based processes have other advantages over wet chemical processes.…”

Abstract. The influence of a pressure of gas mixture (10 vol% O 2 + 90% N 2 ) on an average size of copper oxide nanoparticles, produced in the plasma of low pressure arc discharge, has been studied as a basic process variable. A correlation between the dependence of average particle size on gas mixture pressure and the dependence of discharge gap voltage on product of interelectrode distance by a gas mixture pressure, has been found. The estimation was carried out by means of X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM). A mathematical model of the cathode region, which shows the applicability of the similarity theory to the low pressure arc discharge, has been represented.

“…14,17,19 Plasmabased processes have already been used for the synthesis of iron oxide nanoparticles. [20][21][22] The precursors used in these reported synthesis processes are iron pentacarbonyl and ferrocene. Nanoparticle synthesis in low-pressure plasmas depends on the choice of suitable precursor and process parameters.…”

Iron oxide nanoparticles are synthesized using organometallic precursors namely, iron (III) acetylacetonate and cyclopentadienyliron dicarbonyl dimer in a capacitively coupled low pressure plasma system. They are characterized using High Resolution Transmission Electron Microscopy (HRTEM), X-ray Di®raction (XRD), magnetization studies and Raman spectroscopy. The role of hydrogen and RF (Radio Frequency) power on the crystalline and magnetic properties of the nanoparticles is studied. Incorporation of hydrogen to the Plasma-Enhanced Chemical Vapor Deposition (PECVD) chamber during the synthesis facilitates both crystallization of iron oxide nanoparticles and reduction of carbon content in the product. The saturation magnetization of iron oxide nanoparticles synthesized using iron (III) acetylacetonate and cyclopentadienyliron dicarbonyl dimer in presence of hydrogen at 200 W RF power is higher than that synthesized in the absence of hydrogen at 50 W RF power. In case of nanoparticles Int. J. Nanosci. Downloaded from www.worldscientific.com by NORTHWESTERN UNIVERSITY on 03/25/15. For personal use only.synthesized using iron (III) acetylacetonate, the saturation magnetization increases from 1.5 emu g À1 to 19 emu g À1 , and for the same synthesized from cyclopentadienyliron dicarbonyl dimer it increases from from 3.2 emu g À1 to 22.4 emu g À1 .
