Efficient and Stable Luminescence from Mn²⁺ in Core and Core-Isocrystalline Shell CsPbCl₃ Perovskite Nanocrystals.

ABSTRACT: There has been a growing interest in applying CsPbX₃ (X = Cl, Br, I) nanocrystals (NCs) for optoelectronic application. However, research on doping of this new class of promising NCs with optically active and/or magnetic transition metal ions is still limited. Here we report a facile room temperature method for Mn²⁺ doping into CsPbCl₃ NCs. By addition of a small amount of concentrated HCl acid to a clear solution containing Mn²⁺, Cs⁺, and Pb²⁺ precursors, Mn²⁺-doped CsPbCl₃ NCs with strong orange luminescence of Mn²⁺ at ∼600 nm are obtained. Mn²⁺-doped CsPbCl₃ NCs show the characteristic cubic phase structure very similar to the undoped counterpart, indicating that the
