Zero-dimensional organic–inorganic hybrid manganese bromide with coexistence of dielectric–thermal double switches and efficient photoluminescence

ions. Excitingly, this single crystal's photoluminescence quantum yield (PLQY) is as high as 80.78%. This work provides a strategy for the development of organic-inorganic hybrid optoelectronic multifunctional materials with high-efficient light emission and switchable dielectric properties.
