Perovskites are famous for harvesting light in emerging solar cells, but the inexpensive and easy-to-make semiconductors could also provide a simple path to light-emitting devices.

Commercial white light-emitting diodes are made either by combining different colored LEDs or using LEDs that excite phosphor coatings to produce a white glow. Researchers have previously developed a few two-dimensional perovskite crystals that can emit white light without help, but scientists have yet to use them to build a . . .
