    Immiscibility between dimethyl sulfoxide (DMSO) and polar solvents used for poly(N vinylcarbazole) (PVK) solutions, leads to failed light emitting diodes when colloidal cadmium sulfide (CdS) nanoparticles capped with thiophenol are incorporated to their active layer. To prevent this, a heat treatment is applied to the CdS nanoparticles in order to evaporate DMSO solvent.
