Special Issue Information

Dear Colleagues,

Polyol synthesis has emerged these last years as a powerful and scalable wet-chemistry route for the production of chemically and structurally controlled inorganic nanoparticles. Through a simple optimization of the operating synthesis conditions, it allows the design of well-shaped homo- and hetero-nanostructured metal, oxide, chalcogenide, halogenide, alkoxide, or hydroxide particles, with a great applicative interest for various technological fields, including renewable energy, human health, environment, telecommunications.

This Special Issue invites manuscripts concerning the synthesis of such functional nanoparticles, their characterization and upscaling with a particular emphasis on their applications through their integration in targeted electromagnetic-based devices. Original articles on synthesis strategies will be considered, including the preparation of metastable phases, original microtructures (nanoflowers, core-shell, hetero-coagulate, janus system, etc.), new compounds (carbon dots, etc.), and in situ nanohybrids (self-assembly in polyol, etc.). Articles describing polyol-made nanoparticle shaping (nanoconsolidates, functional inks, thin films, ferrofluids, etc.) and their succesful use in different technological and biotechnological fields are also recommended.

Nanoparticles (NPs) of WO3-x Compounds by Polyol Route with Enhanced Photochromic Properties
Nanomaterials 2019, 9(11), 1555; https://doi.org/10.3390/nano9111555 - 01 Nov 2019

Tungsten trioxide (WO3) is well-known as one of the most promising chromogenic compounds. It has a drastic change of coloration induced from different external stimuli and so its applications are developed as gas sensors, electrochromic panels or photochromic sensors. This paper focuses on the photochromic properties of nanoWO3, with tunable composition (with tunable oxygen sub-stoichiometry). Three reference samples with yellow, blue and black colors were prepared from polyol synthesis followed by post annealing under air, none post-annealing treatment, or a post-annealing under argon atmosphere. These three samples differ in terms of crystallographic structure (cubic system versus monoclinic system), oxygen vacancy concentration, electronic band diagram with occurrence of free or trapped electrons and their photochromic behavior. Constituting one main finding, it is shown that the photochromic behavior is highly dependent on the compound’s composition/color. Rapid and important change of coloration under UV (ultraviolet) irradiation was evidenced especially on the blue compound, i.e., the photochromic coloring efficiency of this compound in terms of contrast between bleached and colored phase, as the kinetic aspect is high. The photochromism is reversible in a few hours. This hence opens a new window for the use of tungsten oxide as smart photochromic compounds. Full article

Polyol-Mediated Synthesis of Nitrogen-Containing Carbon-Dots from Tetracyanobenzene with Intense Red Fluorescence
Nanomaterials 2019, 9(10), 1470; https://doi.org/10.3390/nano9101470 - 16 Oct 2019
Abstract
Nitrogen-containing C-dots were prepared by heating (160 °C, 1 h) 1,2,4,5-tetracyanobenzene (TCB) in polyethylene glycol 400 (PEG400). The as-prepared monocrystalline C-dots were 2–4 nm in diameter and contained 24.4 wt. % of nitrogen. They showed intense fluorescence under excitation at 400–500 nm as [...] Read more.
Nitrogen-containing C-dots were prepared by heating (160 °C, 1 h) 1,2,4,5-tetracyanobenzene (TCB) in polyethylene glycol 400 (PEG400). The as-prepared monocrystalline C-dots were 2–4 nm in diameter and contained 24.4 wt. % of nitrogen. They showed intense fluorescence under excitation at 400–500 nm as well as under excitation at 600–700 nm. In addition to an excitation-wavelength-depending emission at 400 to 650 nm, the emission spectra exhibited a strong emission peaking at 715 nm, whose position was independent from the wavelength of excitation. For this deep-red emission a remarkable quantum yield of 69% was detected. The synthesis of nitrogen-containing C-dotswas completely performed in the liquid phase. Moreover, the C-dots could be directly dispersed in water. The resulting aqueous suspensions of PEG400-stabilized nitrogen-containing C-dots also showed intense red emission that was visible to the naked eye. Full article

Due to the high atomic number of lutetium and the low phonon energy of the fluoride matrix, Lu-based fluoride nanoparticles doped with active lanthanide ions are potential candidates as bioprobes in both X-ray computed tomography and luminescent imaging. This paper shows a method for the fabrication of uniform, water-dispersible Eu3+:(H3O)Lu3F10 nanoparticles doped with different Eu contents. Their luminescent properties were studied by means of excitation and emission spectra as well as decay curves. The X-ray attenuation capacity of the phosphor showing the highest emission intensity was subsequently analyzed and compared with a commercial contrast agent. The results indicated that the 10% Eu3+-doped (H3O)Lu3F10 nanoparticles fabricated with the proposed polyol-based method are good candidates to be used as dual probes for luminescent imaging and X-ray computed tomography.
