On page 1603325, T. Song, B. Q. Sun, and co-workers develop a general solvent selection strategy by taking interaction between quantum dots (QDs) and solvent into consideration. A suitable solvent is obtained to achieve a high quality QDs film for an efficient and uniformly emitting light-emitting diode. This strategy provides a general approach to deposit high quality QDs films for solution-processed multilayer optoelectronic devices.
