Abstract

The formation of nanocrystals in quasi-2D Ruddlesden–Popper perovskite can be spontaneously induced by appropriately timed anti-solvent treatment, as reported by Aleksandra B. Djurišić, Kam Sing Wong, and co-workers in article number 1900269. Only nanocrystals with n = 4 phase are detected, different from commonly obtained mixtures of different phases. The formation of nanocrystals in a disordered matrix results in a significant enhancement of the light emission due to defect passivation.
