Developing inorganic lead-free perovskite for broadband emissionArtificial lighting accounts for one
Developing inorganic lead-free perovskite for broadband emissionArtificial lighting accounts for one-fifth of global electricity consumption, and developing efficient and stable luminescence materials is critical to avoid unnecessary waste of electric energy. The single emitters with broadband emission, such as lead halide perovskites, have recently triggered tremendous attention for artificial illumination and display applications. To develop lead-free and stable perovskites with broadband emission, researchers in China targeted low-dimensional bismuth halide perovskites. They published their work on Apr. 15 in Energy Material Advances.“The single emitters with broadband emission can circumvent critical problems faced in the traditional mixed and multicomponent emitters such as the efficiency losses caused by self-absorption, the complex device structure, and the colors instability due to the different degradation rates of phosphors,” said paper author Rengui Li, a professor with the State Key Laboratory of Catalysis, Dalian National Laboratory for Clean Energy, Dalian Institute of Chemical Physics, Chinese Academy of Sciences (CAS). “Lead halide perovskites have emerged as highly attractive next-generation optoelectronic materials for light-emitting applications due to their extraordinary photoelectric properties.”Read more. -- source link
