Novel luminescent “nano‐bombs” based on a self‐assembled system of carbon‐nanodots, termed supra‐CDs, are developed. The luminescence of these luminescent “nano‐bombs” depends strongly on water contact; they show weak emission in toluene and decompose in contact with water, resulting in strong photoluminescence. Paper coated with these “nano‐bombs” is successfully applied for water‐jet printing of luminescence patterns and the mapping of human sweat‐pore patterns.
