Halide perovskites have a variety of attractive feature such as high quantum yield, and tunable optical properties, combined with easy fabrication. Here, Kirstein et al demonstrate spin-mode locking in CsPb(Cl0.56Br0.44)3 lead halide perovskite nanocrystals embedded in a fluorophosphate glass matrix, and a hole spin lifetime extending into the microsecond range.
