 Project objective

The development of low-cost, clean, and scalable energy solutions is imperative to securing a peaceful and sustainable future. Optoelectronic devices such as light-emitting diodes (LEDs) incorporating new, inexpensive materials show tremendous promise to alter the energy landscape by reducing the cost of energy consumption. However, the widespread adoption of LEDs demands new technologies to surpass the luminous efficacies of conventional LED light while having a full control over colour, brightness and directionality of the light source. Recently, a new class of semiconducting materials, ABX3 perovskites, is poised to revolutionise the LED field due to its ease of processing and outstanding electronic and optical properties. In this context, the ultimate goal of this proposal is the development of the first efficient white light LED based on luminescent nanostructured perovskites that feature tuneable on-demand emission properties. ConPLED will result in an alternative to commercial white LEDs, with the additional gain of having finely tuneable electroluminescence based on cost-effective materials processed at low temperature. The combination of perovskite nanocrystals that show quantum confinement effects with photonic nanostructures, an area where the researcher has demonstrated proficiency, will lead to fine control over the colour gamut, and the angular bandwidth of light emission. A deep understanding of the electro-optical and structural properties of such nanostructured emitting materials will lead to demonstrate efficient white light LEDs, which is one of the main activities of the Optoelectronics group at Cavendish Laboratory (University of Cambridge). The project covers the experimental realization of materials and their integration in devices as well as advanced characterization and performance tests, all of which lies in the common ground of physicists, chemists and technologists and, thus, will naturally broaden the area of expertise of the researcher.
