Observation of Three-Photon Cascaded Emission from Triexcitons in Giant CsPbBr₃ Quantum Dots at Room Temperature.

14 We also note that the BE BX extracted from the pair analysis shows a clear trend of higher BE BX with higher energy of the 1X transition (indicating a stronger confinement and a smaller size, see Figure S4 ), in agreement with previously measured trends for stronger confinement. 14 In weakly confined nanocrystals, Auger recombination is not an effective nonradiative decay mechanism. 20 , 26 , 27 This implies that the second-order correlation at a time-delay of zero, g (2) (0), is likely close to 1.
