红色钙钛矿LED材料设计Material Design For Red Perovskite LED
➀ 中国科学技术大学团队针对红色钙钛矿LED在高亮度下的效率衰减问题，提出新型材料设计方案；
➁ 通过引入3D晶内异质结构和PTLA分子实现载流子局域化抑制电荷泄漏；
➂ 创下24.2%外量子效率、24,600 cd/m²亮度及127小时稳定性的行业新记录。
➀ Researchers at the University of Science and Technology of China developed a new material design for red perovskite LEDs (PeLEDs), solving efficiency loss at high brightness;
➁ The team used a 3D intragrain heterostructure with p-Toluenesulfonyl-L-arginine (PTLA) to confine charge carriers and minimize leakage;
➂ Achieved record-breaking performance: 24.2% external quantum efficiency, 24,600 cd/m² luminance, and 127-hour operational stability.
