Self-organized patterning: Regular and spatially tunable luminescent submicrometer stripes over large areas

A fast and a simple bottom-up method presented using LB technique to generate regular and tunable luminescent stripes with submicrometer-scale lateral dimensions was discussed. It was found that the width and the periodicity of the luminescent stripes could be controlled by adjusting the experimental condition. Adjusting experimental conditions such as the transfer velocity, transfer surface pressure, and dye-to-DPCC ratio, allowed to control the luminescent patterns. The result shows that the formation of regular luminescent stripes could be interpreted by considering substrate-induced microphase separation and periodic oscillation of the meniscus at the three-phase contact line.
