Effect of Solvents of Quantum Dots on QLED Performance

Abstract

The QLED that we are making now, in addition to the evaporation of the a layer, the other layers are generally obtained by solution spin-coating. In our experiments, the selection strategies for quantum dots and adjacent layers of solvents were summarized. Based on these strategies, we selected the appropriate solvent to obtain high quality films, and in order to avoid the quantum dot film laye being corroded, and the surface having streaky defects, thereby hindering the high performance of the device. This solvent selection strategy provides a common method for preparing high quality films for most solution processed multilayer optoelectronic device.
