Chloride ions kill the stability of blue perovskite light emitting diodes
Blue light-emitting diodes represent a fundamental element in the contemporary lighting and display technology landscape. Like prevailing technology such as III-V, organics and quantum dot LEDs, developing efficient and stable blue perovskite light-emitting diodes (PeLEDs) is a formidable challenge. Over the past few years, the research community has experienced a remarkable upsurge in the
