TEM micrograph of AgF solution immediately after manufacture; (a) predominantly spherical silver nanoparticles (arrow) dispersed in the colloidal solution; (b) higher magnification allows verifying the sizes of 7–30 nm of silver nanoparticles; (c) micrograph of solution 12 months after manufacture. The silver nanoparticles (arrow) remained dispersed in the solution after approximately 12 months of preparation (image with 100 nm scale).
