Two-dimensional perovskites with phase-pure structures have considerable potential for optoelectronic applications because of their reduced defects, flattened energy landscape and enhanced lattice protection. This Perspective article investigates advancing progress on achieving phase-pure perovskite by tailoring the precursor interactions and preparation methods and discusses their prominent optoelectronic properties and applications.
