Special Issue Information

Dear Colleagues,

From a nanoscale perspective, it is beneficial to further explore and understand the physical and chemical properties of metal halide perovskites. Metal halide perovskite nanocrystals and thin films, promising new photoelectric materials, have attracted widespread attention in the last few years. Their excellent optical, electronic, and optoelectronic characteristics endow them with a potential application prospects in many fields, such as photovoltaics, lighting, displays, lasers, photodetectors, and high-energy radiation imaging. The nature of nanomaterials not only depend on their crystal and electronic structures, but also on their morphology, dimensions, sizes, ligands, and microenvironment, which will inspire broader fundamental research and optoelectronic applications. Revealing the relevant dynamic mechanisms and constructing structure–activity relationships are both matters of great significance, something will help the design, development and utilization of novel metal halide perovskite nanocrystals and thin films.

This Special Issue aims to collect state-of-the-art contributions related to metal halide perovskite nanocrystals and thin films. The scope of this Special Issue includes, but is not limited to, synthesis, characterizations, modifications, optical properties, exciton dynamics and applications of metal halide perovskite nanocrystals and thin films. We look forward to receiving your contributions, with the purpose of providing a novel and balanced perspective in the field.

Mn2+ doping in metal halide perovskites enables host-to-dopant energy transfer, creating new emission pathways for optoelectronic applications. However, achieving high-efficiency luminescence in 2D systems remains challenging. We synthesized Mn2+-doped 2D PEA2CdCl4 via the hydrothermal method, characterizing its properties through PL spectroscopy, quantum yield measurements, and DFT calculations. Flexible films were fabricated using PDMS and PMMA matrices. The 15% Mn2+-doped crystal showed orange–red emission with 90.85% PLQY, attributed to efficient host-to-Mn2+ energy transfer and 4T16A1 transition. Prototype LEDs exhibited stable emission, while PDMS films demonstrated flexibility and PMMA films showed excellent X-ray imaging capability. This work demonstrates Mn2+ doping as an effective strategy to enhance luminescence in 2D perovskites, with potential applications in flexible optoelectronics and X-ray scintillators. Full article
