Project description
Higher-performance LEDs based on eco-friendly materials
For several decades, light-emitting diodes (LEDs) have used gallium arsenide and gallium phosphide. However, both semiconductors are very expensive to develop. Funded by the Marie Skłodowska-Curie Actions programme, the PHOLED project aims to synthesise new materials that could lead to more sustainable and environmentally friendly LEDs. To this end, researchers will focus on lead-free halide perovskite nanocrystals, a class of optoelectronic materials that emit light over a broad wavelength range. PHOLED will merge expertise in synthetic chemistry, surface chemistry, electrochemistry, photonics and optoelectronics.
Objective
This project (PHOLED) will concentrate on lead-free halide perovskite nanomaterials for their light-emitting diodes (LEDs) application to address the current low-performance issue. The focus of this project will be the synthesis of novel lead-free layered halide double perovskite nanocrystals with surface 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. An 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 such as gallium arsenide and gallium phosphide. 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 fellowship will allow the researcher to incorporate the study of emerging lead-free perovskite nanomaterials-based LEDs into his research profile, broaden his knowledge and offer the researcher further expertise in the fields of eco-friendly, low-cost, and high-performance PeLEDs, opening new horizons for expanding his career prospects. New technical skills and expertise obtained during the fellowship in the beneficiary institute will strengthen the researcher's experimental capabilities and exploit new opportunities in multidisciplinary research domains. This fellowship will also broaden the researcher's networks with world-leading groups in the research of metal halide perovskite-based LEDs.
