Special Issue Information

Dear Colleagues,

Complex metal oxide nanomaterials with perovskite structure in the form of ATiO3 (A = Ba, Sr, Ca, Pb, etc.) are important for a variety of applications in the microelectronics industry, and more recently in nanotechnology. As materials approach nano-scale dimensions, their intrinsic features become subordinated to surface properties, and their functionality extends to a variety of yet unexplored potentials for the production of multifunctional nano-devices with target geometry and controlled chemical and physical properties. Due to their interesting and unique properties, much attention is being given to integrating them in scalable circuit architectures, to work as sensors, actuators, transducers, or energy harvesters.

We invite researchers to submit manuscripts which discuss different synthesis techniques of perovskite nanomaterials, their in-depth characterization, and last but not least, their application possibilities.

Potential topics include a wide range of research in the field, such as:

  • Synthesis of perovskite nanostructures using multiple synthesis techniques resulting in material with different morphologies (particles, rods, tubes, etc.) and properties;
  • Morphology and microstructure characterization;
  • Study and modeling of crystal growth;
  • Property characterization (dielectric, piezoelectric, ferroelectric, semiconducting properties, etc.) and their relationships to external conditions, such as electric field, temperature, humidity, etc.;
  • Integration of perovskite nanomaterials in scalable circuit architectures;
  • Correlation of microstructure to the properties of the synthesized material;
  • Applications of the perovskite materials and prototype demonstration.

The Cs2SnX6 perovskites have attracted much attention due to excellent optoelectronic properties and high stability. In the present work, we have focused on the morphology control and photoluminescence characteristics of the Cs2SnCl6 perovskite crystals. The synthesis process of the Cs2SnCl6 crystals includes two stages composed of the formation of initial crystals and the growth of Cs2SnCl6; the later originated from the oxidization of CsSnCl3. This process has been confirmed by Scanning electron microscope (SEM) and X-rays diffraction (XRD). By controlling the concentration of the initial reactants and hydrochloric acid in the solution to change the supersaturation of the solution, different crystal morphologies, such as truncated octahedron, octahedron, hexapod, quasi-sphere, have been obtained. In relatively a low supersaturation solution, the amount of growth units dominates the crystal growth process to obtain the hexapod and self-assembly crystals. In contrast, in relatively high supersaturation solution, nucleation predominates to yield small size truncated octahedrons and near-spherical Cs2SnCl6 crystals. The synthesized Cs2SnCl6 crystals have shown a wide emission band peaking at 450 nm with full width at half maximum (FWHM) 63 nm due to the defects introduced by Sn2+. The photoluminescence intensities of crystals synthesized at various conditions exhibited considerable difference, which was about 60 times between the highest and the lowest. Full article
