Next-generation light-emitting applications such as displays and opticalcommunications require judicious control over emitted light, includingintensity and angular dispersion. To date, this remains a challenge as con-ventional methods require cumbersome optics. Here, we report highly direc-tional and enhanced electroluminescence from a solution-processed quasi-2-dimensional halide perovskite light-emitting diode by building a devicearchitecture to exploit hybrid plasmonic-photonic Tamm plasmon modes. Byexploiting the processing and bandgap tunability of the halide perovskitedevice layers, we construct the device stack to optimise both optical andcharge-injection properties, leading to narrow forward electroluminescencewith an angular full-width half-maximum of 36.6° compared with the con-ventional isotropic control device of 143.9°, and narrow electroluminescencespectral full-width half-maximum of 12.1 nm. The device design is versatile andtunable to work with emission lines covering the visible spectrum with desireddirectionality, thus providing a promising route to modular, inexpensive, anddirectional operating light-emitting devices.
