A facile, parallel, and controllable approach to fabricating three-dimensional microscale structures with highly fluorescent quantum dots (QDs) over centimeter-sized surface regions is presented. Highly selective layer-by-layer assembly on a surface patterned by microcontact printing produces features of up to twenty QD/polymer bilayers. Hierarchical structures such as (green-QD/red-QD)(n) (see Figure) and (QD1/polymer)(n)(QD1/QD2)(m) are also fabricated.
