(a–f) Temperature dependence of the time-resolved photoluminescence (PL) emission measured for the three different morphologies: (a, b) one layer of large grains (352 nm-CL), (c, d) multilayers of small grains (550 nm-CS), and (e, f) one layer of islands of small grains (103 nm-IS) at 370 nJ/cm2. The blue curves represent the evolution of the emission by increasing the temperature, which is different in the HEB and LEB.
