 Project objective

The proposal aims to produce novel light emitters by merging two promising semiconductor families, III-Nitrides and lead halide perovskite nanocrystals (LHP NCs) into novel nanostructured architectures. III-Nitrides are established emitters with widespread use in the lighting industry and high-density optical disks and with great promises for power electronic applications. On the other hand, the field of LHP NC photonics is at its infancy but breakthroughs have already been accomplished with demonstrations of optically-pumped lasers and light emitting diodes (LEDs). Research on the two material families has thus far proceeded independently. Yet new architectures with improved performance and functionality may emerge from their integration into hybrid devices that can exploit the favourable properties of each, namely the superior electrical properties and established technology of the nitrides with the ease of solution-processability, visible spectral tunability and high emission quantum yields (QY) of the LHP NCs. The proposed project will be investigating the potential flow of energy from the donor material (III-nitrides) to the acceptor (LHP NC), via radiative pumping but also via efficient non-radiative Förster energy transfer (FRET,) under optical and electrical excitation. Additionally is aiming to demonstrate hybrid electrically excited nanostructure devices, allowing the two materials to exist with nanoscale proximity. Moreover, the project is targeting to the fabrication of electrical-excited of a hybrid microcavity-based heterostructures, via an elaborate design of two back to back microcavities. The outcome of this project is expected to particularly benefit the scientific semiconductor area and industry fro the development of efficient high colour rendering index (CRI) LEDs for solid state lighting and display applications.The methodology for a demonstration of novel light emitters is highlighted in work packages (WPs) 3 to 5.
