“…Reactive gases are used as main constituents to form a plasma flame for synthesis of nano-sized materials. Thermal plasma synthesis of M x WO 3 was reported by Mamak et al (2010) in which a powder mixture containing a precursor of (NH 4 ) 10 (H 2 W 12 O 42 ). 4H 2 O and salt of HCOOCs, Na2CO3, and K3C6H5O7 in a varied ratio of W and M were used.…”

Among several active photothermal nanomaterials, tungsten-oxide-based materials have received considerable attention recently because of their ability to absorb near-infrared (NIR) light and their efficient light-to-heat conversion properties. In addition, tungsten-oxide-based materials have an unusual oxygen defect structure and strong local surface plasma resonance (LSPR), which offers strong photoabsorption in a broad wavelength range of the NIR region. In the past, several light-absorbing nanomaterials such as noble metals, polymeric materials, and other inorganic nanomaterials were of interest for their use in photothermal therapy for cancer treatment. In this study, we review the synthesis, properties, and applications of tungsten-oxide-based nanomaterials as a new type of photothermal material. The basic ideas behind photothermal nanomaterial development as well as the factors that influence their structural designs are also discussed in this study. In addition, recent progress in various fields such as NIR light-shielding, pyroelectric, water evaporation, photocatalysis, gas sensors, and energy-related applications for WO 3−x-and M x WO 3-based nanomaterials (including their hybrids) are highlighted. Finally, this review presents promising insights into this rapidly growing field that may inspire additional research leading to practical applications.

An ensemble inhomogeneity of non-spherical LaB 6 nanoparticles dispersion has been analyzed with Mie theory to account for the observed broad plasmon band. LaB 6 particle shape has been characterized using small-angle X-ray scattering (SAXS) and electron tomography (ET). SAXS scattering intensity is found to vary exponentially with exponent À3.10, indicating the particle shape of disk toward sphere. ET analysis disclosed dually grouped distribution of nanoparticle dispersion; one is large-sized at small aspect ratio and the other is small-sized with scattered high aspect ratio, reflecting the dual fragmentation modes during the milling process. Mie extinction calculations have been integrated for 100 000 particles of varying aspect ratio, which were produced randomly by using the Box-Muller method. The Mie integration method has produced a broad and smooth absorption band expanded towards low energy, in remarkable agreement with experimental profiles by assuming a SAXS-and ET-derived shape distribution, i.e., a majority of disks with a little incorporation of rods and spheres for the ensemble. The analysis envisages a high potential of LaB 6 with further-increased visible transparency and plasmon peak upon controlled particle-shape and its distribution. V C 2015 AIP Publishing LLC.

“…The extreme high power, and the ability of feeding solid precursor through the thermal plasma zone results in very high throughputs of more than 300 g of Si‐NPs per hour, which is among the highest Si‐NP processing throughput reported using plasmas . Apart from Si‐NPs, synthesis of various nanoparticles in thermal plasmas such as SiO 2 , SiO x , SiO x –Ti, SiC, TaC, Al 2 O 3 , TiO 2 , and W‐bronze have been reported.…”

Silicon nanoparticles (Si-NPs) are considered as possible candidates for a wide spectrum of future technological applications. Research in the last decades has shown that plasmas are one of the most suitable environments for the synthesis of Si-NPs. This review discusses the unique size-dependent features of Si-NPs, and the fundamental mechanisms of nanoparticle formation in plasmas by highlighting major plasma synthesis techniques. In addition, the routes to achieve control on Si-NP morphology and chemistry in plasma environments will be discussed. We will review recent advancements in solar cell and lithium-ion battery applications of gas-phase plasma synthesized Si-NPs by highlighting key results from the literature. We will discuss further technological applications, where gasphase plasma synthesized Si-NPs can contribute, like water splitting and thermoelectrics.
