研究:单层纯蓝色超荧光OLED,稳定性高、低成本

基于热激活延迟荧光的蓝色有机发光二极管,存在稳定性低和发射范围宽的问题。超荧光Hyperfluorescence(在热激活延迟荧光发射体上,产生的激发态被转移到具有窄发射光谱的荧光终端发射体)有望提高颜色纯度和稳定性。然而,在较小间隙终端发射极上,直接电荷俘获导致直接发射损失、抑制电荷传输和电荷不平衡。

China’s grip on drone supply chain spurs South Korea to boost self-reliance

A recent surge in the cost of Chinese-made drone components has reignited concerns in South Korea over its overwhelming reliance on China for critical unmanned aerial vehicle (UAV) parts. South Korea is accelerating efforts to boost domestic manufacturing capabilities and enhance collaboration with the US to fortify its drone industry and mitigate strategic risks.
