Synthesis of CsPbCl3‐Mn Nanocrystals via Cation Exchange

Mn doped caesium lead halide perovskite (CsPbCl3‐Mn) nanocrystals are obtained from CsPbBr3 nanocrystals via ion exchange with MnCl2. The doping of Mn and the activity in energy acceptance in different stages of ion exchange are proved using photoluminescence (PL) lifetime measurement and inductivel...

Description
Summary:Mn doped caesium lead halide perovskite (CsPbCl3‐Mn) nanocrystals are obtained from CsPbBr3 nanocrystals via ion exchange with MnCl2. The doping of Mn and the activity in energy acceptance in different stages of ion exchange are proved using photoluminescence (PL) lifetime measurement and inductively coupled plasma mass spectrometry measurements. During the ion exchange, ultrasonic treatment and cold flow (in a KCl matrix) are used to assist Mn incorporation. The resulting CsPbCl3‐Mn@KCl shows excellent PL properties and stability. Finally, the CsPbCl3‐Mn@KCl tablet is applied to the production of a light emitting diode prototype.
