Opto-thermal modelling & design of quantum-dot-on-chip LEDs

In lighting and display technology, quantum dots can bring the combined benefit of enhanced performance and reduced power consumption, and lead to tailored-spectrum-by-design light sources. The goal of this PhD research encompasses both the modelling, design and realization of optimized quantum-dot-on-chip LEDs for different applications including LED displays, general lighting and specialty lighting (horticulture, architectural). To design efficient quantum dot LEDs with tailored emission spectra, realistic optical models have to be developed. Monte Carlo ray-tracing is a prime candidate to do this. Apart from the optical performance, optimized thermal management solutions will be equally important. This is mainly because thermal quenching of quantum dots starts at lower temperatures than the typical phosphors that are used in today’s white LEDs. Because thermal effects have an impact on the optical performance and vice versa, it will be necessary to couple both thermal and optical simulations.
