Self-organized luminescent stripe patterns (see Figure) with submicrometer-scale lateral dimensions are obtained by transferring dye/phosphatidylcholine mixed monolayers onto a solid substrate by means of Langmuir–Blodgett deposition. The regular luminescent stripe formation can be interpreted as a substrate-induced microphase separation and a periodic oscillation of the meniscus at the three-phase contact line.
