A ‘‘ball-on-film’’ template is developed to construct concentric rings on the surface of PMMA-QDs (polymethyl methacrylate-quantum dots) nanocomposite films via the evaporation of chloroform droplets. The concentric rings consist of PMMA and QDs, and the photoluminescence intensity of the concentric rings associated with the amount of QDs increases with the increase of the distance to the ball center. Both the wavelength and cross-sectional area (width) of the concentric rings increase approximately linearly with increasing the distance to the ball center. Using a template of ‘‘two spheres on film’’, surface patterns on PMMA-QDs nanocomposite films is also constructed. Symmetric surface patterns are formed with two types of featureless zone between the two balls; one is the inner featureless zone, and the other is the outer featureless zone. The size of both featureless zones increases with the increase of the ball distance.
