Researchers have achieved precise control of the size of quantum dots by using the quantum confinement effect. Rb+ and Cs+ with similar ionic radii have become a new mechanism for researchers to regulate the emission wavelength of quantum dots. However, there are few studies on the performance of codoped quantum dots with ion at present. By adding a saturated solution of RbCl into an organic solution of CsPbBr3, quantum dots doped with Rb+ and Cl− were prepared. The prepared quantum dots realized adjustable emission spectrum (457‐510 nm), stable lattice structure, and good stability under ultraviolet light irradiation. Therefore, double ion doping is a new method to prepare short‐wavelength of quantum dots. [ABSTRACT FROM AUTHOR]
