SEM images of AgCl microstructures by one-pot hydrothermal process at different reaction times. (a) After 10 h of reaction, abundant nucleated AgCl cubic seeds appear, which began to show preferential overgrowth along <111> direction; insert is a growing 'flower’ preferential growth from a cubic-faceted crystals seed. (b,c) The same image with different schematic labels, which is the cube in (a) grows to symmetric flower-like octagonal crystals after 11 h of reaction.
