Size dependence on cooling rate and nanoparticle concentration. Representative fluorescence microscopy images of spherical shells formed from ligand-modified quantum dots (LC-QDs) at a–c fixed LC-QD concentration of 0.3 wt% in 5CB, varying cooling rate, and d–f fixed cooling rate of 200 °C min−1, varying LC-QD concentration in 5CB. g Qualitative phase diagram for the three distinct morphologies predominantly observed as a function of cooling rate and concentration. General morphological zones on the diagram are indicated by the colored boxes with circle size representative of structure size. h, i Plots of average shell diameter vs. cooling rate and concentration respectively, with error bars indicating standard deviation (s.d.); the total number of measured structures, n, ranged from 10 to 183 (Supplementary Table 1)
