Opportunities and challenges of chiral perovskites for spin-LEDs

Chiral perovskites have drawn intensive attention in recent years due to their promising optospintronic applications. In this forum article, the unique properties of chiral perovskites and their applications in circularly polarized light emission (CP-LE) and spin light-emitting diodes (LEDs) are briefly introduced, along with the challenges and plausible prospects in this field.
