Noncoherent Frequency-Shift Keying for Ambient Backscatter Over OFDM Signals
IEEE Open Journal of the Communications SocietyIn this paper, we investigate frequency shift keying (FSK) over ambient orthogonal frequency division multiplexed (OFDM) signals. By cycling through a sequence of antenna loads providing different phase shifts at the tag, we are able to unidirectionally ...

Advanced Optical Materials, Volume 13, Issue 36, December 19, 2025.Fullerene acceptor‐based organic photodetectors show sub‐optimal device performance due to deep trap states originating from undesirable adduct formation between donor and acceptor with unfavorable bulk‐heterojunction morphology. This work demonstrates subphthalocyanine‐based non‐fullerene acceptor (like Cl6‐SubPc) has great potential for trap‐free ...

First Tellurite Composite Fiber with NIR‐Driven Green Persistent Luminescence
Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.The first composite fiber based on SrAl2O4:Eu2+, Dy3+ PeL phosphors embedded in Yb3+/Tm3+ co‐doped tellurite glass is developed. The fiber exhibits green afterglow driven by 980 nm laser injection, suggesting that the PeL phosphors survive the fabrication process and the blue upconversion from the Yb3+/Tm3+ co‐doped glass matrix is strong enough to ...
