SINGLE-LAYER BLUE LEDS BASED ON A PEROVSKITE– POLYMER COMPOSITE
Keywords:
blue LED, halide perovskites, perovskite-polymer compositeAbstract
A practical solution to the challenge of simple and stable blue LEDs is proposed: a solution-processed single-layer device based on a perovskite–polymer composite. Stable blue electroluminescence at low operating voltages is demonstrated, and prospects for further optimization and practical implementation are outlined.References
