Two-dimensional (2D) layered perovskites recently emerged as one of the most promising materials for optoelectronics. These not only behave like a quantum well structures, but also on doping Mn(II) ions at the Pb site result as a highly emissive doped material. These structures can also be used as a starting material for obtaining 3D perovskites. Thermal treatment of Mn(II)-incorporated layered perovskites in presence of Cs(I) ions led to Mn(II)-doped 2D platelet–shaped perovskites, which also tune their dimensions with varying dopant ion concentrations. Keeping the importance of the 2D-layered perovskites, this review focused on the basic structures to the recently developed synthetic strategies and their optical properties of layered structured perovskites, Mn(II)-doped layered perovskites, and Mn(II)-doped 2D platelet–shaped perovskites.

二维（2D）层状钙钛矿最近成为光电技术中最有前途的材料之一。这些不仅表现得像量子阱结构，而且在Pb位置掺杂Mn（II）离子时，也产生了高发射率的掺杂材料。这些结构也可用作获得3D钙钛矿的起始材料。在Cs（I）离子存在下对掺入Mn（II）的层状钙钛矿进行热处理会导致Mn（II）掺杂的2D片状钙钛矿，这也会随着掺杂离子浓度的变化而调整其尺寸。保持2D层钙钛矿的重要性，本综述着眼于最近开发的合成策略的基本结构及其层状结构钙钛矿，Mn（II）掺杂的层钙钛矿和Mn（II）掺杂的2D血小板的光学性质。形钙钛矿。
