The past decade has witnessed the growing interest in metal halide perovskites as driven by their promising appliions in diverse fields. The low intrinsic stability of the early developed organic versions has however hampered their widespread appliions. Very recently, all-inorganic perovskite nanocrystals have emerged as a new class of materials that hold great promise for the practical
