A simple and dry method for colloidal semiconductor nanocrystal (NC) deposition on soluble organic semiconductor layers is developed, consisting of spin coating followed by poly(dimethylsiloxane) transfer. This technique is used to deposit a homogeneous layer of mixed red, green, and blue CdSe/ZnS quantum dots onto an organic multilayer structure (see picture) and to fabricate a heterojunction hybrid organic/inorganic white‐light‐emitting diode.
