Enhanced Dual-Emission Properties of Mn-Doped CsPbCl<sub>3</sub>/ZIF-8 Nanocomposites for Display
Mn-doped CsPbX3 quantum dots (QDs) are recognized for their dual-emission characteristics and low lead content, making them valuable in display applications. In this study, dual-emission peaks at 406 and 589 nm were achieved in Mn-doped CsPbCl3 QDs through a high-temperature thermal injection method. The 406 nm peak is sourced from the QD host, while the 589 nm peak results from Mn doping. Enhancement of both emission peaks is observed when Mn-doped QDs are integrated with ZIF-8 material via in situ growth, leading to a greater than 3-fold increase in emission intensity. The resulting composite material demonstrates considerable stability, retaining over 40% intensity under UV light, 50% under continuous heating at 100 °C, and 44% in air exposure after 25 days. These results highlight the potential of nanomaterials for high-performance optoelectronic devices.
