Abstract

We present a general protocol to prepare metal halide perovskite films for LEDs exceeding 17% EQE, with improved stability, and as flexible as organic electronic thin films. Finally, we show stabilized mixed halide (I and Br) and mixed Pb-Sn stoichiometries such that we can tune emission from the green to near infrared.
