Special Issue Information

Dear Colleagues,

Research interest in nanocrystals has continued to rapidly grow during the last decade. Such efforts include the development of new synthesis methods, opinions and insights of advanced structural understanding, and exploration of novel properties. The study of these nanocrystal-based materials has promoted the improvement and advancement of structural, optical, magnetic and electronic characterization techniques in the nanoscale. Investigation of nanocrystals has also demonstrated both the academic and technological importance, and offered great research opportunities within cross-disciplinary areas.

I invite authors to contribute original research articles or comprehensive review papers, including the most recent progress and new development in the synthesis, characterization, assembly, design and analysis, utilization and application of nanocrystals. This Special Issue aims to cover a broad spectrum of this subject, from experimental preparation to theoretical prediction. The format of welcomed manuscripts consists of research articles, review articles and short communications. Potential nanocrystal topics include, but are not limited to:

  • Novel synthesis and characterization of nanocrystals;
  • Nanocrystal structure and manipulation;
  • 2D and 3D assembly of nanocrystals, superlattices and superstructure determination;
  • Development of advanced methods for nanocrystal analysis;
  • Theoretical design and prediction of nanocrystals and supercrystals;
  • Nanocrystal and supercrystal simulation;
  • Nanocrystals for chemical, (photo-) catalytic and electrocatalytic applications;
  • Nanocrystals for electronic, photonic and optoelectronic applications;
  • Nanocrystals for sensing, magnetic, thermal, thermoelectric, photovoltaic, battery and supercapacitor applications;
  • Nanocrystals for nanomedicine (such as drug delivery), diagnostic, imaging, labeling and other biological/medical applications;
  • Nanocrystals for environmental, energy and sustainability applications, and for other related topics.

ZnSnO3 semiconductor nanostructures have several applications as photocatalysis, gas sensors, and energy harvesting. However, due to its multicomponent nature, the synthesis is far more complex than its binary counter parts. The complexity increases even more when aiming for low-cost and low-temperature processes as in hydrothermal methods. Knowing in detail the influence of all the parameters involved in these processes is imperative, in order to properly control the synthesis to achieve the desired final product. Thus, this paper presents a study of the influence of the physical parameters involved in the hydrothermal synthesis of ZnSnO3 nanowires, namely volume, reaction time, and process temperature. Based on this study a growth mechanism for the complex Zn:Sn:O system is proposed. Two zinc precursors, zinc chloride and zinc acetate, were studied, showing that although the growth mechanism is inherent to the material itself, the chemical reactions for different conditions need to be considered.

The ionic transportation and dielectric properties of YF3:Eu3+ nanocrystals are investigated by AC impedance spectroscopy. The ion diffusion coefficient and conductivity increase along with the doping concentration and reach their highest values at 4% of Eu3+. The difference of ionic radius between Eu3+ and Y3+ leads to the structural disorder and lattice strain, which deduces the increase of the ion diffusion coefficient and conductivity before 4% Eu3+ doping; then the interaction of the neighboring doping ions is dominated, which results in the difficulty of ion migration and decreases of the ion diffusion coefficient and conductivity. The strong dispersion of the permittivity in the low frequency region indicates that the charge carrier transport mechanism is the ion hopping in the system. The low-frequency hopping dispersion is affected by an interfacial polarization, which exhibits a Maxwell-Wagner relaxation process, and its loss peak shifts to higher frequency with the ionic conductivity increasing.
