N2 - The luminescence and charge transport properties of inorganic CsPbX3 perovskite nanocrystals (NCs) make them attractive candidates for
various optoelectronic applications, such as lasing, X-ray imaging, light communication, and light-emitting diodes (LEDs). However, to
realize cutting-edge device performance, high-quality NCs with high photoluminescence quantum yields (PLQYs) are essential. Therefore,
substantial efforts and progress have been made to attain superior design/engineering and optimization of the inorganic NCs with a focus
on surface quality, reduced nonradiative charge carrier recombination centers, and improved colloidal stabilities. Metal-ion doping has been
proven to have a robust influence on the electronic band structure, PL behavior, and charge carrier recombination dynamics. Thus, in this
perspective, we summarize the recent progress of the significant impact of metal cation doping on the optical properties, including the PL
enhancement of CsPbCl3, CsPbBr3, and CsPbI3 perovskite NCs. Moreover, we shed light on the mechanism behind such improved properties. We conclude by recommending possible aspects and strategies to be further explored and considered for better utilization of these doped NCs in thin-film optoelectronic and energy conversion devices.
