Transition metal perovskite chalcogenides are a new class of versatile semiconductors with high absorption coefficient and luminescence efficiency. Polycrystalline materials synthesized by an iodine-catalyzed solid-state reaction show distinctive optical colors and tunable bandgaps across the visible range in photoluminescence, with one of the materials' external efficiency approaching the level of single-crystal InP and CdSe.
过渡金属卤化物钙钛矿是一类具有高光吸收系数和发光效率的新型多功能半导体。碘催化的固态反应合成的多晶材料在光致发光中表现出独特的光学颜色和可调带隙，横跨可见光范围，其中一种材料的外部效率接近单晶 InP 和 CdSe 的水平。
