浸渍提拉镀膜仪文献：低速浸涂法制备掺杂染料的光致发光有机乙烯吡咯烷酮杂化膜的蒸发驱动自组装

We prepared silica-poly(vinylpyrrolidone) (PVP) hybrid films containing a photoluminescent organic dye, rhordamine 6G (R6G), by low-speed dip-coating, where the spontaneous pattern formation was induced in the films. Stripe patterns arranged perpendicular to the substrate withdrawal direction were spontaneously formed by stick-slip motion at the meniscus during dip-coating, and the film structure (i.e., the film thickness, and the height, width and spacing of stripe patterns) was changed with increasing amounts of volatile solvent (C 2 H 5 OH) in solutions (C 2 H 5 OH/Si(OCH 3 ) 4 mole ratio (x) = 20–150). As a result of the optimization of the film structure, localized photoluminescence at the stripe patterns was achieved over x = 120.
