Mass production of Mn2+-doped CsPbCl3 perovskite nanocrystals with high quality and enhanced optical performance

Abstract

In the present work, an improved hot injection technique, namely microwave-assisted hot injection, for mass production of Mn2+-doped CsPbCl3 (Mn2+:CsPbCl3) perovskite nanocrystals (NCs) was reported. This strategy combines the advantages of both microwave irradiation and hot injection, which represents characteristics such as homogeneous heating and rapid production of Mn2+:CsPbCl3 NCs with a homogeneous size distribution. Meanwhile, it exhibits the capacity for gram-scale synthesis of Mn2+:CsPbCl3 NCs. The Mn2+ doping concentrations can be facilely tailored by controlling the reaction temperatures and feed ratios of the MnCl2 precursor, resulting in their enhanced optical properties with a PL QY up to 65%, which is the highest among the Mn2+-doped perovskite NCs ever reported. The as-constructed light emitting diodes (LEDs) based on Mn2+:CsPbCl3 NCs emit highly bright white light, suggesting their potential applications in optoelectronic devices.
