All inorganic cesium lead halides (CsPbX₃, X=Cl, Br, I) are promising materials and have been developed in recent years for various optoelectronic devices and applications because of their excellent optoelectronic properties. Regardless of their excellent characteristics their stability is still uncertain and it is challenging task to obtain stable emission in CsPbX₃ perovskite quantum dots (PQDs), hence limiting their practical optoelectronic application. In this context, several approaches have been used like an-ion exchange, ion doping, and core–shell structure to enhance PQDs stability. Herein, we synthesized dual ion co-doped Al³⁺/Mn²⁺ CsPbCl₃ PQDs for stable light emitting diodes through traditional hot injection method for the first time. By adjusting molar concentration of Al³⁺/Mn²⁺ CsPbCl₃, co-doped PQDs were successfully prepared. The co-doped PQDs exhibit tunable emission, covering a wide range under UV excitation. Moreover, these high luminescent co-doped PQDs were used to fabricate WLEDs, displaying stable near white light emission with the chromaticity coordination at (0.35, 0.28). Some new evidence has emerged, although some aspects of Mn²⁺ and Al³⁺ doping are considered to be consistent with previous conclusions. This viewpoint incorporates all of these details and focuses on the path of transition metal ion doping to perovskite nanostructures and offers an overview for possible potential studies.

所有无机卤化铯铯（CsPbX ₃，X = Cl，Br，I）都是有前途的材料，由于其优异的光电性能，近年来已开发用于各种光电器件和应用。不管其优异的特性如何，其稳定性仍不确定，要在CsPbX ₃钙钛矿量子点（PQDs）中获得稳定的发射是一项艰巨的任务，因此限制了其实际的光电应用。在这种情况下，已经使用了多种方法来增强PQD的稳定性，例如阴离子交换，离子掺杂和核壳结构。在这里，我们合成了双离子共掺杂的Al ³⁺ / Mn ²⁺ CsPbCl ₃首次通过传统的热注入方法为稳定的发光二极管提供PQD。通过调节Al ³⁺ / Mn ²⁺ CsPbCl _3的摩尔浓度，成功制备了共掺杂的PQD 。共掺杂的PQD表现出可调的发射，在紫外线激发下覆盖了很宽的范围。此外，这些高发光共掺杂PQD用于制造WLED，显示出稳定的近白光发射，色度坐标为（0.35，0.28）。尽管Mn ²⁺和Al ^3+的某些方面出现了一些新的证据掺杂被认为与先前的结论一致。该观点结合了所有这些细节，并着重于过渡金属离子掺杂到钙钛矿纳米结构的途径，并为可能的潜在研究提供了概述。
