Abstract

Although there are many works focusing on tuneable photoluminescence(PL) character of Manganese(Mn)-doped perovskite nanocrystals(PNCs), systematically studying the influence of cations (such as Zn2+, Sn2+ and Mg2+) and anions (such as Cl-) on the Mn emission intensity is uncultured. Here, based on a modified method, hydrochloric acid(HCl), the single and simplest Cl- precursor, is firstly used to tune the Mn emission intensity of PNCs prepared under high temperature. By limiting the Cl sources and introducing other cations (Zn2+, Sn2+ and Mg2+) in the reaction system, the Mn emission intensity of final PNCs could be tuned negatively. Besides, this is the first time to realize co-doping Zn and Mn ions into PNCs during the formation of PNCs. In addition, the as-prepared stable doped PNCs have been used as active materials in light emitting devices(LEDs), which display orange emission.
