Quantum Dot-Induced Kinetic Bottleneck in Singlet Exciton Relaxation of Conjugated Polymer Aggregates

Yeon Gyu Kim, Se Gyo Han, Minyoung Jeong, Taeyong Ha et autres

Abstract We designed hybrid aggregate model systems with cascade energy alignment from conjugated polymers (CPs) to quantum dots (QDs) to investigate the effects of QDs on CP singlet (S1) excitons. Radiative recombination of S1 excitons occurs within 1 ps in the chlorinated …

Annealing‐Free Gradient Doping Strategy to Build Amorphous Nb:TiO X Electron Transport Layer for Efficient Perovskite Solar Cells

Fang Luo, Dongbo Zhang, Shaozheng Chen, Ye-Won Lee et autres

(NTO) electron transport layers (ETLs) via dynamic co-sputtering with controlled power modulation. This method produces a vertically graded composition (Ti-rich at the bottom and Nb-rich at the top) -without requiring any post-deposition thermal treatment. The resulting NTO films exhibit a smooth, amorphous …

Improving prognostic stratification in adult-type diffuse glioma using unsupervised spatiotemporal perfusion-based tumor habitat analysis

Junhyeok Lee, Joon Ik Jang, Inpyeong Hwang, Seung Hong Choi et autres

Motivation: Gliomas exhibit heterogeneity within and between tumors, affecting treatment responses and patient outcomes. Goal(s): This study aimed to investigate the association between tumor habitat heterogeneity, derived from DSC-MRI imaging, and progression-free survival (PFS) as well as overall survival (OS) in patients …
