Perovskite nanocrystals-in-glass hierarchical structures enable stable continuous-wave random lasers.

ABSTRACT: Encapsulating perovskite nanocrystals (PNCs) in glass enables enhanced stability of PNCs and numerous applications such as random lasers. However, preparing PNCs and tuning their properties in glass is energy consuming because of high processing temperature and long processing time, and continuous-wave (CW) random lasers have not been achieved. Here, we report modulation of the structure, photoluminescence, and lasing properties of PNCs in glass at temperatures well below the glass transition temperature with a short processing period. We generate tunable PNCs in glass via nanophase separation and ion exchange in the perovskite domains. PNCs-in-glass hierarchical structures are created by controlling nanophase separation and crystallization of PNCs. Substantially increased scattering in th
