Special Issue Information

Dear Colleagues,

We are pleased to announce a Special Issue titled “Advanced Nanomaterials and Coating Technologies for High-Performance Electronic, Optoelectronic, Energy, and Sensing Devices”. This Special Issue highlights recent advances in oxide semiconductor nanomaterials, essential for developing next-generation electronic, optoelectronic, energy, and sensing technologies.

We invite researchers to submit original research, reviews, and case studies on topics such as the synthesis, functionalization, and applications of oxide semiconductor nanomaterials. This Special Issue aims to foster insights into oxide semiconductor structures, interfaces, and functional properties. Topics of interest include the following:

  • Theoretical and experimental studies on growth mechanisms and synthesis methods;
  • Functional properties and their dependency on synthesis parameters;
  • Methods to enhance electrical, magnetic, and optical properties;
  • Advanced characterization techniques and applications in sensing and energy storage.

Accepted papers will undergo rigorous peer review and will be published online, making them widely accessible to the scientific community. We look forward to your contributions and to advancing the field together.

Abstract
In this study, tin oxide (SnO2)/polyaniline (PANI) composite nanowires (NWs) with varying amounts of PANI were synthesized for carbon dioxide (CO2) gas sensing at room temperature (RT, 25 °C). SnO2 NWs were fabricated via the vapor–liquid–solid (VLS) method, [...] Read more.
In this study, tin oxide (SnO2)/polyaniline (PANI) composite nanowires (NWs) with varying amounts of PANI were synthesized for carbon dioxide (CO2) gas sensing at room temperature (RT, 25 °C). SnO2 NWs were fabricated via the vapor–liquid–solid (VLS) method, followed by coating with PANI. CO2 sensing investigations revealed that the sensor with 186 μL PANI exhibited the highest response to CO2 at RT. Additionally, the optimized sensor demonstrated excellent selectivity for CO2, long-term stability, and reliable performance across different humidity levels. The enhanced sensing performance of the optimized sensor was attributed to the formation of SnO2-PANI heterojunctions and the optimal PANI concentration. This study underscores the potential of SnO2-PANI composites for CO2 detection at RT. Full article

Abstract
The second-generation phosphorescent organic light-emitting diodes are formed using phosphorescent emitters, which can theoretically achieve 100% internal quantum efficiency. However, these emitting materials usually suffer from triplet–triplet annihilation (TTA) and/or concentration-quenching effects. To address the disadvantages, host–guest systems are used in the emitting [...] Read more.
The second-generation phosphorescent organic light-emitting diodes are formed using phosphorescent emitters, which can theoretically achieve 100% internal quantum efficiency. However, these emitting materials usually suffer from triplet–triplet annihilation (TTA) and/or concentration-quenching effects. To address the disadvantages, host–guest systems are used in the emitting layer, where the guest is dispersed into a host matrix. Carbazole is one of the most commonly used electron-donating fragments, which is widely applied as a building block for the synthesis of the mentioned host materials. In this review article, we describe the synthesis, thermal, electrochemical, and optoelectronic properties of the hosts with carbazolyl units as well as application of the matrixes in the phosphorescent devices. This review is written from the perspective of structural chemistry and the host materials are divided in several groups as 9-arylcarbazoles, twin derivatives containing two carbazolyl fragments, 3(2)-aryl(arylamino)-substituted, and 3,6(2,7)-diaryl(diarylamino)-substituted carbazoles.
