Special Issue Information

Dear Colleagues,

We are delighted to invite you to submit your recent research related to organic–inorganic metal halides to this Special Issue. Organic–inorganic metal halides have emerged as a family of materials with outstanding optical and electrical properties, owing to their exceptional structural tunability and designable organic and inorganic moieties. Organic–inorganic metal halides have been applied extensively in solid-state lighting, solar cells, light-emitting diodes, lasers, photocatalysis, scintillators, ferroelectrics, sensors, etc. Nevertheless, further expanding the material library with new organic or inorganic moieties in order to elucidate their design rules is necessary. In addition, characterizing and explaining their optical, electronical and other unique properties is of great importance.

This Special Issue aims to collect papers that report the recent advances made in this family of materials and that provide insight into their intriguing properties, especially their optoelectronic properties. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  1. Material development;
  2. Interaction with other substances;
  3. Stimulation response;
  4. Mechanism study;
  5. New characterization methods.

I eagerly look forward to receiving your contributions.

Thin films of zinc oxide (ZnO) doped with transition metals have recently gained significant attention due to their potential applications in a wide range of optoelectronic devices. This study focuses on ZnO thin films doped with the transition metals Co, Fe, and Zr, exploring various aspects of their structural, morphological, optical, electrical, and photoluminescence properties. The thin films were produced using RF and DC co-sputtering techniques. The X-ray diffraction (XRD) analysis revealed that all the doped ZnO thin films exhibited a stable wurtzite crystal structure, showcasing a higher structural stability compared to the undoped ZnO, while the atomic force microscopy (AFM) imaging highlighted a distinctive granular arrangement. Energy-dispersive X-ray spectroscopy was employed to confirm the presence of transition metals in the thin films, and Fourier-transform infrared spectroscopy (FTIR) was utilized to investigate the presence of chemical bonding. The optical characterizations indicated that doping induced changes in the optical properties of the thin films. Specifically, the doped ZnO thin film’s bandgap experienced a significant reduction, decreasing from 3.34 to 3.30 eV. The photoluminescence (PL) analysis revealed distinguishable emission peaks within the optical spectrum, attributed to electronic transitions occurring between different bands or between a band and an impurity. Furthermore, the introduction of these transition metals resulted in decreased resistivity and increased conductivity, indicating their positive influence on the electrical conductivity of the thin films. This suggests potential applications in solar cells and light-emitting devices. Full article
