Abstract
Mn doped cesium lead halide perovskite nanocrystals (NCs) have potential application for white light emitting diodes. However, the emission of doped NCs is limited to trap-mediated energy transfer. The Mn doped CsPbCl3 NCs with corporation of rubidium (Rb+) ions (Mn:Cs1-xRbxPbCl3 NCs, x = 0, 0.1, 0.2, 0.3, and 0.4) were synthesized. The effect of the optical and structural properties of Mn:Cs1-xRbxPbCl3 NCs were studied by steady-state and time-resolved photoluminescence spectroscopy. The photoluminescence quantum yields and lifetimes of Mn doped CsPbCl3 NCs with different Rb+ contents were obtained. It was found that the Mn doped CsPbCl3 NCs with Rb+ content of 0.1 exhibited the highest Mn2+ emission quantum yield up to 63.18%. Interestingly, the temperature-dependent PL spectra demonstrated the enhanced Mn2+ emission of Mn doped CsPbCl3 NCs at low temperature of 80 K. The experimental result indicated the Mn2+ emission of Mn doped CsPbCl3 NCs was enhanced by incorporating Rb+ ions.
