Omfattande fotofysikalisk studier av nanokristaller av blyfri halogenidperovskit: mot miljövänliga och högpresterande ljusemitterande dioder

This project (PhOLED) will concentrate on lead-free halide perovskite nanomaterials for their light-emitting diodes (LEDs) application to address the low-performance issue. The focus of this project will be the synthesis of novel lead-free layered double perovskite nanocrystals with surface engineering and doping engineering, and the corresponding mechanism studies, which account for the fabrication of high-performance perovskite LEDs (PeLEDs). PhOLED will combine multidisciplinary research crossing synthetic chemistry, surface chemistry, electrochemistry, photophysics, and optoelectronics. The completion of PhOLED will result in the generation of new knowledge to synthesize novel lead-free perovskite nanocrystals with outstanding optoelectronic properties which can provide crucial hints for chemists to enable further optimization of high-quality lead-free perovskite nanomaterials. The achievement of low-cost and high-performance lead-free-based PeLEDs from PhOLED will significantly highlight the possibility of the replacement of conventional LEDs that are made of exotic semiconductors. The replacement of toxic lead by less- or non-toxic lead-free metals achieved by PhOLED will also have benefits for both environment and human beings. This project will allow the appointed postdoctoral researcher to incorporate the study of emerging lead-free perovskite nanomaterials-based LEDs into the research profile, broaden the knowledge and offer the researcher further expertise in the fields of eco-friendly, low-cost, and high-performance PeLEDs. New technical skills and expertise generated and obtained under the supervision of the applicant (PI: Maning Liu) at Lund University will strengthen the researcher’s as well as the team’s experimental capabilities and exploit new opportunities in multidisciplinary research domains. PhOLED will also broaden the networks with world-leading groups in the research of metal halide perovskite-based optoelectronics.
