The widespread adoption of solution-processed halide perovskites LEDs demands to surpass the luminous efficacies of conventional LEDs while having full control over the emission properties.
In this talk, we report directional and enhanced emission in a green perovskite LED through hybrid photonic-plasmonic modes. We employ advanced optical modelling powered by genetic algorithms to find the best combination of materials and structures compatible with the fabrication of efficient LEDs. The experimental realisation of the optimum designs allows us to show low-temperature processed devices with enhanced emission and fine control over the emission angle. This methodology is versatile and easily integrable in cost-effective LEDs across the whole visible spectrum, opening avenues for their application in displays and light sources where the angular dispersion of light is crucial.
