Optical properties of Mn-doped CsxRb1−xCdCl3 provskites and hmidity sability

  • A series of x%Mn:CsCdCl3 perovskite materials were synthesized by a simple solvent method at room temperature, and the structure and optical properties of the CsCdCl3 with different Mn2+ ion doping concentration were studied through the characterization of the structure and optical properties. On this basis, the A-site Rb alloying further regulates its optical properties. The results show that low-concentration Mn2+ ion doping can effectively enhance the photoluminescence (PL) emission intensity of CsCdCl3, and the intensity reaches the maximum when the Mn2+ ion doping concentration is 1%. Further, Rb alloying at the A site show that the introduction of a small amount of Rb+ ions can further enhance the PL quantum yields (QY) of CsCdCl3, reaching the maximum when the Cs/Rb ratio is 3:1. In addition, compared with the PL intensity after treatment for 5 h in an environment with a relative humidity of 100%, the stability of alloyed 1%Mn:Cs0.75Rb0.25CdCl3 sample has a relatively higher level than the unalloyed 1%Mn:CsCdCl3 sample.
