2D/3D heterostructure derived from phase transformation of 0D perovskite for random lasing applications with remarkably improved water resistance

Abstract

exhibited no sign of light amplification even pumped much harder. The pump threshold and the PL spectral profile were well maintained upon recycling treatment with water, implying the water resistance capability of the developed random lasing. The results suggest that the 2D/3D perovskite composites derived from the phase transformation of their 0D counterpart can serve as promising platforms for nanophotonic applications.
