Large-scale perovskite light-emitting diodes enabled by quantum-wire arrays: One step closer to commercialization

Halide perovskite light-emitting diodes (PeLEDs) are enticing candidates for displays and lighting. However, it remains a challenge for devices to upscale to large-area or non-planar structures with high uniformity. Recently, in Nature Photonics, Fan and co-workers developed perovskite quantum-wire arrays templated by porous alumina membranes to achieve highly uniform performance LEDs based on wafer-scale substrates and three-dimensional spherical structures.
