Diffraction-limited, high-contrast photopatterning of the photoluminescence of layer-by-layer films comprising CdSeCdS@ZnS quantum dots and polyviologen is reported. The photoluminescence of the quantum dots is initially quantitatively quenched due to ultrafast photoinduced electron transfer to polyviologen. Photopatterning is achieved by high-power or prolonged illumination in air, which photochemically degrades the polyviologen and thereby restores the photoluminescence of the quantum dots
