Project description DEENESFRITPL High-performance light-emitting devices Europe’s Energy Strategy includes measures to ensure the development of more efficient and cost-effective light-emitting diodes (LEDs). Improved devices with low production cost on large-area and light substrates were realised by a combination of colloidal quantum dots (QDs) and metal halide perovskites (PSs). However, the investigation of the interactions of both materials is in the early phase, as concrete knowledge about their performance is lacking. The EU-funded LED4Nature project will focus on designing innovative, lead-free, QD@2D-PS hybrids, improving their composition through studying their electro-optical properties, and describing their performance in LED devices. The project will provide essential information for the development of LED devices based on these hybrid materials, which will have significant industrial and socioeconomic impacts. Show the project objective Hide the project objective Objective In line with the European Energy Strategy on H2020, intensified research on the development of more-efficient and cost-effective light emitting diodes (LEDs) is required. In this regard solution processable colloidal quantum dots (QDs) and metal halide perovskites (PS) showed excellent proficiency to realize effective devices with low fabrication cost on large-area and light-weight substrates. Despite the high potentiality of developing advanced LEDs by exploiting the combination of PS and QDs, the investigation of the interactions of both materials is still in its early stage; and much is yet to be discovered regarding the charge-transport dynamics, mobilities, and defect states in different compositions of these hybrid materials. Our project's research objectives address this crucial issue and focus on designing novel, lead-free, QD@2D-PS hybrids, optimize their composition through studying their electro-optical properties, and finally characterize their performance in LED devices. The project (LED4Nature) will provide detailed knowledge about the effectiveness of Sn based 2D PS as a matrix for lead-free near-IR emitting QDs, and understanding of the effect of structural modifications (QD size, shell thickness, and PS's cation) on their spatially- and temporally- resolved photo-induced phenomena by time-resolved transient absorption and femtosecond terahertz spectroscopy, along with fluorescence lifetime imaging microscopy. Such information will be essential for the optimization and acceleration in the development of LED devices based on these hybrid materials which will be achieved through planned secondments to an expert group- and is expected to have significant industrial and socio-economic impacts. Comprehension of such multidisciplinary project will not only provide the fellow excellent research training, but will also provide a skill-set of transferable skills which will improve and diversify the fellow's future employment perspectives.
