## Description

- description: Organic–inorganic hybrid halide perovskites have been explored extensively
    for optoelectronic functional materials. Here, we report (110)p-oriented layered
    halide perovskite thin films with nominal compositions of FA4Pb2(BrxI1−x)7.5(SCN)0.5
    (x = 0, 0.25, 0.5, 0.75, and 1). X-ray diffraction measurements and UV-visible
    diffuse reflectance measurements demonstrate the successful formation of a solid
    solution between iodide and bromide. The band gap gradually changes from 2.18
    eV to 2.81 eV with increasing Br content, and PL emission of 750 nm was observed
    for the x = 0 film. We also report a single crystal sample of x = 1.
