2D GIWAXS pattern of 2-PeOH/PhAD+ post-treated MeBz- (a, c) and MeBz/KOH- (b, d) based PQD solid films at incident angles of 0.2° (a, b) and 0.8° (c, d). e Azimuthally integrated GIWAXS intensity at incident angles of 0.2° and 0.8° of 2-PeOH/PhAD+ post-treated MeBz- and MeBz/KOH-based PQD solid films. KPFM images and corresponding surface potential distributions (f, g), AFM images (h, i), and 2D pseudo-color PL lifetime maps (j, k) of 2-PeOH/PhAD+ post-treated MeBz- (f, h, j) and MeBz/KOH- (g, i, k) based PQD solid films.
