Special Issue Information

Dear Colleagues,

In recent years, optically active materials have attracted considerable interest due to their high potential for the development of technological devices. There is a broad range of materials that can be utilized for optical components, including both organics and inorganics. In this sense, new advanced optical materials are being intensively studied for their technological applications such as lasers, color displays, light emitting diodes, sensors, solar cells, and optical amplifiers.

The aim of this Special Issue, titled “Advances in Luminescent Materials: Fabrication and Technological Applications”, is to highlight the latest advances in luminescent research. Its scope covers the synthesis and structural characterization of materials, the study of optical properties, and possible technological applications.

The topics of interest include the following:

  • Processing methods;
  • Structural and functional characterization;
  • Optically active polymers, crystals, and glass ceramics;
  • Rare-earth doped materials;
  • Laser technology;
  • Nanophotonic materials;
  • Nonlinear photonics;
  • Optical amplifiers;
  • Optoelectro-mechanical systems;
  • Optical devices;
  • Optical materials;
  • Optical sensors;
  • Photonic applications;
  • Color displays;
  • Ultrafast optoelectronics;
  • Anti-counterfeiting.

It is a great pleasure to invite you to submit a manuscript to this Special Issue. Full articles, letters, short communications, tutorials, and reviews are welcome. All submitted works will undergo a rigorous pre-check and peer-review process to ensure the highest scientific quality and relevance to this collection of papers.

This study investigates the interfacial structural origin of enhanced optical performance in InP-based quantum dots (QDs) employing a 2-step ZnSe shelling strategy. By comparing InP/ZnSe/ZnS QDs synthesized via 1-step and 2-step shelling methods using identical InP cores, we demonstrate that the 2-step approach [...] Read more.
This study investigates the interfacial structural origin of enhanced optical performance in InP-based quantum dots (QDs) employing a 2-step ZnSe shelling strategy. By comparing InP/ZnSe/ZnS QDs synthesized via 1-step and 2-step shelling methods using identical InP cores, we demonstrate that the 2-step approach results in improved core–shell lattice matching, more favorable carrier dynamics, and enhanced thermal stability. These enhancements are attributed to the formation of an initial thin ZnSe interfacial layer, which facilitates uniform shell growth and suppresses interfacial defect formation. High-resolution transmission electron microscopy and elemental mapping via energy-dispersive X-ray spectroscopy analyses confirm the improved crystallinity and reduced oxygen-related trap states in the 2-step samples. The findings highlight the critical role of interfacial control in determining QD performance and establish the 2-step ZnSe shelling strategy as an effective route to achieving structurally and optically robust QD emitters for advanced optoelectronic applications.
