Perovskite light-emitting diodes (PeLEDs) have great potential in solid-state lighting and display fields due to their advantages of narrow emission spectrum, excellent optoelectronic properties, simple preparation process, and low cost. However, the compatibility of solvents used in the full solution process substantially hindered the development of multilayer white PeLEDs. Although mixing perovskite and organic materials can avoid this problem, it remains challenging to manufacture white PeLEDs that are close to the Commission Internationale ...
