Impact of bright-dark exciton thermal population mixing on the brightness of CsPbBr$_3$ nanocrystals
Understanding the interplay between bright and dark exciton states is crucial for deciphering the luminescence properties of low-dimensional materials. The origin of the outstanding brightness of lead halide perovskites remains elusive. Here, we anal
