Abstract

The invention relates to a preparation method of Mn-doped CsPbCl3 perovskite nano-crystals and belongs to the technical field of material preparation. The Mn-doped CsPbCl3 perovskite nano-crystals areprepared by a microwave-assisted thermal injection method. The Mn-doped CsPbCl3 perovskite nano-crystals are uniform in size, and the doping concentration of Mn is adjustable and is 0.1-32 percent compared with that of Pb. The Mn-doped CsPbCl3 perovskite nano-crystals prepared by the microwave-assisted thermal injection method are uniform in size and high in quality; the method for preparing theMn-doped CsPbCl3 perovskite nano-crystals, provided by the invention, can quickly synthesize the Mn in large quantities and is simple and controllable in process; through adjusting the reaction temperature, the doping of different concentrations can be effectively achieved, therefore, the repeatability is good.

Description

technical field

[0001] The present invention relates to a kind of Mn-doped CsPbCl 3 (Mn 2+ -CsPbCl 3 ) A method for preparing perovskite nanocrystals belongs to the technical field of material preparation. Background technique

[0002] All inorganic CsPbX 3 (X=Br, Cl, I) perovskite due to its excellent optical properties, such as: continuously adjustable in the visible light range, narrower half-width, faster fluorescence lifetime and faster electron mobility, etc., make It has good application prospects in the fields of solar cells, light-emitting diodes, lasers, and photoelectric detection. Mn ion doping can give semiconductor materials new optical and electromagnetic properties. Manganese-doped perovskites have been reported and show better performance than intrinsic materials. Currently synthesized Mn 2+ -CsPbCl 3 The main method of nanocrystals is the hot injection method. Although this method can obtain nanocrystals with uniform size and excellent optical proper...
