a,c, Evolution of the PLQY of an ensemble of 30 nm and 7 nm CsPbBr3 QDs, respectively. The absolute PLQY was measured at 77 K and projected to lower temperatures via the relative PL intensity ratio. Both samples show over 90% PLQY at 4 K. b,d, The PL spectra at 4 K and 77 K for the two studied samples.
