In this work, efficient pure blue InP/ZnSe/ZnS/ZnS QDs with emission wavelength of 470 nm are synthesized by optimizing the thick shell structure. Residual zinc stearate coated on QDs is removed successfully which facilitates the injection of holes. External quantum efficiency can reach to 1.7% for pure blue InP QLED.
