Herein, we report Sn2+ doping in FAPbI3 NCs to stabilize the α-phase, while using propionic acid as a co-ligand. The Sn2+ doping enhances the emission quantum yield from 35% to 63% and dramatically improves the colloidal and phase stability. Also, we demonstrated the use of Sn doped FAPbI3 NCs in near-infrared (NIR) LEDs.
在此，我们报道了在FAPbI3纳米晶中掺杂Sn2+以稳定α相，同时使用丙酸作为共配体。Sn2+掺杂将发射量子产率从35%提高到63%，并显著提高了胶体稳定性和相稳定性。此外，我们展示了掺Sn的FAPbI3纳米晶在近红外（NIR）发光二极管中的应用。
