Herein, we reported a mechanochemical synthesis for incorporating divalent manganese ions (Mn<sup>II<\/sup>) into a two-dimensional (2D) hybrid perovskite (C<sub>4<\/sub>H<sub>9<\/sub>NH<sub>3<\/sub>)<sub>2<\/sub>PbCl<sub>4<\/sub>. The mild external stimuli originating from the grinding at room temperature enabled the formation of MnII-doped 2D hybrid perovskites, and rapidly changed the luminescence characteristics. The photoluminescence analyses show that the violet and orange emissions are attributed to (C<sub>4<\/sub>H<sub>9<\/sub>NH<sub>3<\/sub>)<sub>2<\/sub>Pb<sub>1\u2013<em>x<\/em><\/sub>Mn<sub><em>x<\/em><\/sub>Cl<sub>4<\/sub>&nbsp;band-edge emission and the T<sub>1<\/sub>\u2192<sup>6<\/sup>A<sub>1<\/sub>&nbsp;transition of Mn<sup>2+<\/sup>&nbsp;resulting from an efficient energy transfer process, respectively. Site preference and distribution of the doped Mn<sup>2+<\/sup>&nbsp;cations on the locations of Pb<sup>2+<\/sup>&nbsp;were analyzed. The formation energy calculated by the density functional theory (DFT) indicates that the Mn<sup>2+<\/sup>&nbsp;ions can rapidly enter the crystal lattice due to the unique 2D crystal structure of the hybrid perovskite. Such a case of mechanochemical synthesis for the 2D hybrid perovskite motivates many novel emerging materials and the related applications.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sci.
