Mn2+掺杂Cs3Cu2I5微晶的温和、快速溶液法合成
Mild and Rapid Solution Synthesis of Mn2+-doped Cs3Cu2I5 Microcrystals
摘要
Abstract
Doping Mn2+ into the copper-based halide Cs3Cu2I5 is an important approach to broaden the lumines-cence performance.However,most of the reported doping methods require high temperature,inert atmosphere,long reaction time,and specialized equipment.In this work,by directly adding CsI powders into a hydroiodic acid solu-tion of CuI and MnCl2,Mn2+-doped Cs3Cu2I5 microcrystals were rapidly synthesized at a relatively low temperature(60℃)under ambient air conditions within 3 minutes.Through a series of control experiments,we propose a"slow-release growth-doping"mechanism controlled by the solubility of the reactants.It is confirmed that the slow dissolu-tion rate of CsI powders in a concentrated hydroiodic acid can reduce the growth rate of Cs3Cu2I5 crystals,providing favorable kinetic conditions for controllable Mn2+ doping.This work provides a new approach for the study of doping luminescence and doping kinetics in all-inorganic metal halide systems.关键词
