Special Issue Information

Dear Colleagues,

The development of novel nanocomposite materials with enhanced physical and chemical properties is one of the emergent topics of recent years. Since the development of affordable and available commercially nanomaterials, nanocomposites have become a most desirable product. The development of novel nanocomposites with enhanced optical properties has become of great interest for domains such as data transmission, sensors, nonlinear optics devices, etc. Electric/dielectric nanocomposites are significant in the research of novel supercapacitors or other renewable energy applications, nanocomposites with specific surface properties have become extremely attractive for antistatic, antibacterial and photocatalytic functional surface applications, and enhanced mechanical properties are desirable for a plethora of needs in transportation, home appliances, architectural applications. Simultaneously possessing more than one functionality is possible when employing nanocomposite materials if the synergistic effect of nano-components/matrix properties is achieved. The present Special Issue aims to address a broad range of subjects, from nanocomposite synthesis/fabrication, to the design and characterization of various nanocomposite materials with enhanced optical, electrical, mechanical, and surface-related properties, to the practical application of nanocomposites. The format of welcome articles includes original full papers, communications, and reviews.

Potential topics include, but are not limited to, the following:

  • Nanocomposite materials with enhanced optical properties;
  • Nanocomposite materials with enhanced electrical properties;
  • Nanocomposite materials with enhanced surface related properties;
  • Nanocomposite materials with enhanced mechanical properties.

The main objective of this study was to determine the variation in the properties of cadmium telluride (CdTe) thin films deposited on a p-type Si substrate by the radio frequency magnetron sputtering technique at four different working powers (70 W, 80 W, 90 W, and 100 W). The substrate temperature, working pressure, and deposition time during the deposition process were kept constant at 220 °C, 0.46 Pa, and 30 min, respectively. To study the structural, morphological, and optical properties of the CdTe films grown under the mentioned experimental conditions, X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and optical spectroscopy were used. For a better analysis of the films’ structural and optical properties, a group of films were deposited onto optical glass substrates under similar deposition conditions. The electrical characterisation of Ag/CdTe/Al “sandwich” structures was also performed using current–voltage characteristics in the dark at different temperatures. The electrical measurements allowed the identification of charge transport mechanisms through the structure. New relevant information released by the present study points towards 90 W RF power as the optimum for obtaining a high crystallinity of ~1 μm nanostructured thin films deposited onto p-Si and optical glass substrates with optical and electrical properties that are suitable for use as absorber layers. The obtained high-quality CdTe nanostructured thin films are perfectly suitable for use as absorbers in CdTe thin-film photovoltaic cells. Full article

The development of multimodal nano- and micro-structures has become an increasingly popular area of research in recent years. In particular, the combination of two or more desirable properties within a single structure opens multiple opportunities from biomedicine, sensing, and catalysis, to a variety of optical applications. Here, for the first time, we report the synthesis and characterization of multimodal chiroptically active CaCO3 nanocomposites. These composites have been prepared by a modified microemulsion method in the presence of an amino acid (cysteine). Following this, additional modalities have been introduced by loading the composites with luminescent nanoparticles or doping with Eu3+ ions. The luminescent composites have been produced by the incorporation of CuInZnS/ZnS or CdSe@ZnS/ZnS core/shell quantum dots, or via doping with trivalent europium. In this manner, we have produced chiroptically active composites with orange, green, and red luminescence. Overall, this work demonstrates the unique advantage and potential of our approach and new class of chiroptically active CaCO3 nanocomposites, which display tunable functionality to specific requirements via the incorporation of desired ions, nanoparticles, and chirality of the structure.
