Special Issue Information
Dear Colleagues,
Light-emitting materials and devices have been at the forefront of technological advancements across optoelectronics, communication, health care, and sensing applications. Over recent decades, the development of novel luminescent materials—including organic semiconductors, carbon nanodots, quantum dots, and perovskites—has opened up new opportunities for designing highly efficient, flexible, and tunable light-emitting devices. These materials have led to innovations in devices such as light-emitting diodes (LEDs), laser diodes, and advanced optical sensors.
Recent progress in nanofabrication techniques and device architecture design has significantly enhanced the performance and multi-functionality of these systems. At the same time, challenges remain in achieving long-term operational stability, scalable manufacturing, and environmentally sustainable processes. Understanding the fundamental photophysical mechanisms through advanced characterization methods is crucial for optimizing efficiency, lifetime, and functionality of light-emitting materials and devices.
This Special Issue invites contributions from researchers working on the cutting edge of material development and device fabrication. We welcome original research articles, comprehensive reviews, and case studies that address challenges and opportunities in this dynamic field, aiming to bridge fundamental science with technological innovation.
Recommended topics include, but are not limited to, the following:
- Synthesis of light-emitting materials:
- Organic, inorganic, hybrid, and perovskite emitters;
- Quantum dots and carbon dots.
- Design and fabrication of light-emitting devices:
- OLEDs, QD-LEDs, and perovskite LEDs;
- Laser diodes and novel luminescent devices.
- Characterization techniques for light-emitting materials and devices:
- Spectroscopic analysis;
- Time-resolved photoluminescence;
- Imaging;
- Light-emitting materials for sensing applications:
- Optical sensors based on luminescence changes;
- Bio-sensing and environmental monitoring.
We encourage submissions that combine theoretical, experimental, and computational approaches and those that explore interdisciplinary applications of light-emitting materials and technologies.
We look forward to receiving your valuable contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
