Luminescence properties of CsPbBr3:Mn nanocrystals
Source abstract
Abstract
Mn-doped CsPbBr3 nanocrystals with sizes of ~10 nm are synthesized by hot injection method via the addition of HBr in the precursor. The sizes and crystal structure are not influenced by the addition of HBr. The photoluminescence (PL) mechanism of CsPbBr3 is modified by HBr, leading to the PL peak shift to 433 nm, which is not the regular PL of CsPbBr3. The irregular CsPbBr3 nanocrystals prepared with HBr enable the Mn doping, leading to the red emission of Mn. The PL energy transfer from CsPbBr3 to Mn is studied as a function of HBr. The energy transfer of ~90% is achieved in this system. In addition, the crystallinity of the CsPbBr3 nanocrystals is also improved by the HBr, leading to better photodetector device performance.
