Synthesis of highly luminescent CsPb2Br5 nanoplatelets and their application for light-emitting diodes
چکیده انگلیسی
Although all-inorganic perovskite CsPbBr3 perovskites quantum dots (QDs) have garnered enormous interest in light emitting diodes, nonetheless limited attention has been paid to the perovskite-related CsPb2Br5 nanoplatelets. Herein, we prepared perovskite-related CsPb2Br5 nanoplatelets (NPLs) by a facile injection method. The synthesised CsPb2Br5 NPLs showed single tetragonal crystalline phase with a uniform square shape and a high photoluminescence (PL) emission around 520 nm (PL quantum yield (QY) > 85%). In addition, we have demonstrated the fabrication of highly efficient CsPb2Br5 NPLs-based green light emitting diodes with the highest luminance of 800 cd/m2 and a relative low turn-on voltage of 3.0 V.
