Synthesis, Properties, and Applications of Perovskite Nanocrystals and Their Composites

Dear Colleagues,

Perovskite nanocrystals (PNCs) have emerged as transformative materials in optoelectronics due to their exceptional photophysical properties, including high photoluminescence quantum yields, tunable bandgaps, and solution processability. These attributes position PNCs as promising candidates for applications in light-emitting diodes (LEDs), solar cells, photodetectors, and quantum technologies. Despite rapid advancements, challenges such as controllable synthesis mechanism,  the precise control of surface chemistry, and stability under ambient conditions persist.

Furthermore, integrating PNCs into composite matrices offers opportunities to enhance functionality and durability while unlocking novel hybrid properties. This Special Issue focuses on addressing these scientific and technological gaps, emphasizing the interdisciplinary nature of PNC research and its critical role in advancing sustainable energy and next-generation optoelectronic devices.

We invite you to contribute to the Special Issue, “Synthesis, Properties, and Applications of Perovskite Nanocrystals and Their Composites”, hosted in Molecules. Aligned with the journal’s scope of publishing cutting-edge research on functional nanomaterials and their technological applications, this issue aims to compile high-quality studies on PNC design, characterization, and device integration. We welcome submissions that bridge fundamental insights with practical innovations, ensuring the collection remains focused yet impactful.

This Special Issue seeks original research and reviews on themes including (1) novel synthetic strategies for PNCs and composites, (2) structure–property relationships and stability enhancement mechanisms, (3) advanced characterization techniques (e.g., in situ spectroscopy, computational modeling), (4) applications in LEDs, photovoltaics, lasing, and sensing, and (5) environmental and scalability assessments. Submissions addressing eco-friendly synthesis, interfacial engineering, and scalable fabrication are particularly encouraged. By curating diverse perspectives, this issue aims to accelerate the translation of PNC innovations into real-world technologies while fostering interdisciplinary collaboration.
