ZnO has excellent chemical stability and thermal stability. In addition, since it has a wide band gap, light transmittance in the visible light region is high. Therefore, ZnO is known to be the most suitable electron transport material. However, it continues to be problematic due to surface defects and dispersion stability problems. Therefore, ZnS shells are stacked to protect the core and introduce a new organic ligand to increase distributed stability. In addition, we investigated the properties of electron carriers stacked with ZnS shells using ZnMgO cores instead of ZnO cores. This optimal shell structure simultaneously achieves high dispersion stability and excellent electron mobility of electron transport materials. This study highlights the importance of proper shell thickness in the structural design of electron carriers.
