The present work reports cadmium-free colloidal ZnS:Al quantum dot (QD) based white quantum dot lightemitting diodes (QD-LEDs). The device was fabricated with a structure of ITO/PEDOT:PSS/ PVK/QDs/TPBi/ LiF/Al using synthesized ZnS:Al QDs which has 393 nm of peak wavelength and sub peaks in visible wavelength. White emission with high color rending index (CRI) was achieved by the combination of blue emission from PVK and ZnS:Al QDs, electroplex emission at the interface between PVK and ZnS:Al QDs, and Al traps/ defects emission, which are controlled by electrical aging effect. The characteristic of our device shows the potential for spectrum tunable and Cd-free white QD-LEDs in the near future.
