A FUS-activated, flexible multicolor display enabled by color-tunable mechanoluminescence. (a) Schematic of a full-gamut 3×3 array with three primary colors: blue (SMSO colloids alone), green (SMSO/CsPbBr3@SiO2 composites), and red (SMSO/CsPb(Br0.3I0.7)3@SiO2 composites). (b) Brightfield photograph of a 3×3 array made of pixels containing SMSO colloids alone, SMSO/CsPbBr3@SiO2 composites, and SMSO/CsPb(Br0.3I0.7)3@SiO2 composites. (c) Afterglow image of the pixel array shown in b. (d) An overlay of the afterglow image with the mechanoluminescence image, the latter of which was taken when FUS was focused at the central pixel of the array. (e) Mechanoluminescence images of the pixel array when FUS is focused at each of the 9 pixels. (f) Brightfield photograph of the array under bending. (g) Afterglow image of the pixel array shown in f. (h) Mechanoluminescence image of the bent pixel array when FUS is focused at the central pixel of the array. (i) An overlay of the afterglow image in g with the mechanoluminescence image in h.
