By exploiting Tamm plasmon modes, Ooi et al. report highly directional and enhanced electroluminescence in quasi-2D perovskite LEDs with angular FWHM of 36.6° and spectral FWHM of 12.1 nm. The photonic platform is versatile and tuneable across the visible spectral range with directionality up to 40°.
