SnO2 nanoparticles (NPs) have emerged as promising electron transport materials for quantum dot light-emitting diodes (QLEDs), but usually encountering poor solution stability against the compatibility of the device fabrication process. In this work, we have successfully synthesized uniformly sized and distributed SnO2(o-SnO2) NPs by employing tin 2-ethyl hexanoate (an organotin compound) precursor with the sol-gel method. The obtained o-SnO2 NPs have superior stability over the conventional SnO2 (c-SnO2) NPs synthesized by a hydrothermal method. In detail, the o-SnO2 NPs can be stably dispersed in ethanol without further addition of dispersant and remain transparent even stored in air for several weeks. Furthermore, the o-SnO2 NPs have been adopted to achieve high-quality electron transport layers (ETLs) with smooth and dense films, which showed a roughness of 1.9 nm, much smaller than 6.53 nm of the c-SnO2 films, showing a competitive candidate for efficient ETLs toward high-performance QLEDs.
