Special Issue Information

Dear Colleagues,

It is well known that optoelectronic applications have grown exponentially in recent decades, which has caused the need for systems with increasingly specific properties that satisfy the increasing specificity of various devices. Coatings and thin films are now required in imaging systems, both in medical systems (MRI, X-rays, computed tomography, nuclear medicine, ultrasound, magnetic resonance, etc.) and in the following systems: TV, cell phones, PCs, etc. Furthermore, new applications have appeared in the field of security systems, biological systems, intelligent thermal barriers, astronomy, etc.

We are thrilled to extend our invitation to you, urging your valuable contributions to this Special Issue. We welcome original research and review articles that expand fundamental knowledge and explore the vast technological applications for luminescent coatings and thin films.

This Special Issue aims to disseminate innovative research that allows the analysis of the effect between synthesis, chemical composition, deposition methods, theorical studies, computational simulations, or industrial applications in luminescent coatings and thin films.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Theoretical and experimental research for luminescent coatings and thin films;
  • Recent advances in luminescent coatings and thin films;
  • A new generation of luminescent coatings and thin films;
  • Industrial applications;
  • Deposition techniques for luminescent coatings and thin films;
  • Morphological, structural, and mechanical properties of luminescent coatings and thin films; 
  • Ceramics films;
  • Hybrid films;
  • Polymeric films.

We look forward to receiving your contributions.

A double-layer core–shell photocatalytic coating was engineered on carbon fibers (CFb) derived from bamboo pulp precursors, employing a sequential process involving seed pre-loading, solvothermal treatment, and impregnation. XRD, SEM, and SEM-EDS analyses revealed that g-C3N4 and Bi2O3 nanosheets were co-assembled on the carbon fiber skeleton, and 50 nm MoS2 particles were successfully loaded, resulting in the fabrication of MoS2/g-C3N4/Bi2O3/CFb photocatalytic fibers. UV–vis spectroscopy, transient photocurrent response, and EIS tests demonstrated that the introduction of narrow-bandgap visible-light photocatalysts (g-C3N4 and MoS2) enhanced light absorption and improved the separation and migration efficiency of photogenerated electron hole pairs. Photocatalytic degradation experiments of MB showed that MoS2/g-C3N4/Bi2O3/CFb significantly outperformed g-C3N4/Bi2O3/CFb and Bi2O3/CFb, achieving a degradation efficiency of 92% within 60 min. Band structure calculations and analysis confirmed the formation of Z-scheme heterojunctions between g-C3N4 and Bi2O3, as well as between MoS2 and Bi2O3. This dual Z-scheme heterojunction endowed MoS2/g-C3N4/Bi2O3/CFb with enhanced redox capabilities, providing a novel strategy for developing efficient photocatalytic materials. Full article
