Aggregation‐induced circularly polarized luminescence and delayed fluorescence enabled by activating high‐level reverse intersystem crossing by Ke Wang, Xinwen Ou, Xiaofei Niu, Zhenghao Wang, Fengyan Song, Xiaobin Dong, Wu‐jie Guo, Hui‐Qing Peng, Zujin Zhao, Jacky W. Y. Lam, Jianwei Sun, Hongkai Wu, Shu‐Yan Yu, Fei Li, Ben Zhong Tang

“…Circularly polarized delayed fluorescence was found to be enabled by activating high‐level reverse intersystem crossing (hRISC). The anti‐Kasha phosphorescence at 77 K proves that the exciton has a large population in the high‐lying triplet state T2, which allows the effective hRISC process to cross back to the singlet state S1 and emit delayed fluorescence. …”

Millimeter-scale radioluminescent power for electronic sensors by Averal N. Kandala, Sinan Wang, Joseph E. Blecha, Yung-Hua Wang, Rahul K. Lall, Ali M. Niknejad, Youngho Seo, Michael J. Evans, Robert R. Flavell, Henry F. VanBrocklin, Mekhail Anwar

“…We describe the potential to address the sensor energy requirement in a two-step process by first converting alpha radiation into light, which can then be translated into electrical power through a photovoltaic harvester circuit protected by a clear sealant. Different phosphorescent and scintillating materials were mixed with the alpha-emitter Th-227, and the conversion efficiency of europium-doped yttrium oxide was the highest at around 2%. …”

The Glowport – Illuminated vitrectomy trocar cannulas by Prithvi Chandrakanth, Shishir Verghese, KS Chandrakanth, Priya Basaiawmoit, Verghese Joseph

“…We report the use of a frugal, fluorescent “glow-in-the-dark” ring placed over vitrectomy cannulas to visualize the cannula entry, thereby providing a smooth and efficient instrument exchange. We 3D-printed phosphorescent rings of optimum inner diameter to comfortably fit around the trocar cannula (The Glowport). …”
