Zero-Dimensional Bismuth Halide Thin Films with High Orientation and Broadband Emission

Abstract Lead-free low-dimensional metal halides are emerging as highly tunable materials for optoelectronic applications. Here, we report a new class of zero-dimensional bismuth halides incorporating phenethylammonium (PEA) cations, namely PEA4BiI7 and PEA4BiBr7, and investigate...
