The tunability of the colors and emissions of quantum‐dot (QD) films —by controlling the deposition order and number of bilayers in (PDDA–CdSe@CdS) n and (PDDA–CdTe) n films (PDDA: poly(diallyldimethylammonium chloride))—is demonstrated. The photograph shows QD microstructures that exhibit different emission colors on a gold nanoparticle (AuNP)‐treated indium tin oxide substrate, fabricated by combining layer‐by‐layer assembly with photolithography.
