TL;DR: The doping of the transition-metal ion Mn in these nanocrystals quenches this strong defect state emission and predominantly shows the spin-flip Mn emission, which can be the ideal versatile materials for widespread technological applications.
Abstract: Multinary nanocrystals (CuInS2, CIS, and AgInS2, AIS) are widely known for their strong defect state emission. On alloying with Zn (CIZS and AIZS), stable and intense emission tunable in visible and NIR windows has already been achieved. In these nanocrystals, the photogenerated hole efficiently moves to the defect-induced state and recombines with the electron in the conduction band. As a result, the defect state emission is predominantly observed without any band edge excitonic emission. Herein, we report the doping of the transition-metal ion Mn in these nanocrystals, which in certain compositions of the host nanocrystals quenches this strong defect state emission and predominantly shows the spin-flip Mn emission. Though several Mn-doped semiconductor nanocrystals are reported in the literature, these nanocrystals are of its first kind that can be excited in the visible window, do not contain the toxic element Cd, and provide efficient emission. Hence, when Mn emission is required, these multinary nanocrystals can be the ideal versatile materials for widespread technological applications.

TL;DR: This Perspective focuses on the insights of doping and the photoluminescence properties of Mn2+-doped perovskite nanocrystals, and proposes possible future prospects of both synthesis and optical properties of these nanomaterials.
Abstract: Doping Mn2+ in semiconductor nanocrystals is widely known for its long-lifetime Mn d–d orange emission. While this had been extensively studied for chalcogenide nanostructures, recently this was al...
