Metal Nanocluster Single Emissive Layer White Light-Emitting Diodes with EQE of 7.3%

Guizhong Luo, Fujun Zhang, Zexin Yu, Zhenyu Wang et autres

While white light-emitting diodes (LEDs) based on metal nanoclusters (NCs) are currently widely desired, due to limitations in the difficulty of controlling emission wavelengths and the susceptibility of luminescence performance to external influences, metal NC white light-emitting diodes (WLEDs) are still not …

Softening of Electron‐Acoustic Phonon Coupling via Core Symmetry Breaking in Metal Nanoclusters

Weinan Dong, Le Hong, Yingguo Yang, C. Cindy Fan et autres

ABSTRACT The core‐skeleton braced low‐frequency acoustic responses, linked to mechanical vibrations, are vital for the reactivity and functionality of a few‐nanometer metal nanoclusters (NCs). Yet, how core‐structure‐dependent acoustic vibrations impact and enhance the luminescence of metal NCs is not fully understood. Using …

Unlocking High External Quantum Yield for Broadband Near‐Infrared Emission From Lead‐Free Perovskite Variant Solid Solutions Cs 2 Te 1‒ x Mo x Cl 6

Xin Li, Yongcheng Zhu, Jinming Yan, Terefe Tafese Bezuneh et autres

ABSTRACT Broadband near‐infrared (NIR) phosphor‐converted LEDs are efficient light sources for imaging, sensing, and security. However, the development of NIR phosphors has been limited by a strategy that prioritizes internal quantum efficiency (IQE) while leaving absorption efficiency (AE) largely underexplored, causing the …

Suspended waveguide-enhanced near-infrared photothermal spectroscopy for ppb-level molecular gas sensing on a chalcogenide chip

Kaiyuan Zheng, Hanyu Liao, Fengbo Han, Xueying Wang et autres

On-chip waveguide sensors have attracted significant attention recently due to their potential for high level integration. However, so far on-chip gas sensing based on traditional laser absorption spectroscopy has demonstrated low detection sensitivity, due to weak light-gas interaction over a limited interaction …

Dual slow-light enhanced photothermal gas spectroscopy on a silicon chip

Kaiyuan Zheng, Hanyu Liao, Yijun Huang, Haihong Bao et autres

Integrated photonic sensors have attracted significant attention recently for their potential for high-density integration. However, they face challenges in sensing gases with high sensitivity due to weak light-gas interaction. Slow light, which dramatically intensifies light-matter interaction through spatial compression of optical energy, …

Bioinspired Mode-Noise Suppressed Off-Axis Integrated Cavity for Rapid Dynamic Gas Detection

Lei Zhang, Xiangyu Luan, Hongyang Jin, Zixun Geng et autres

An innovative off-axis integrated cavity (OAIC) mimicking the tail flagellum of bacteria is proposed to solve the problems of mode interference noise and slow gas exchange caused by the nonuniform gas-flow field in traditional OAIC with large inside airflow fluctuation. The design …

Photoacoustic Ringdown Spectroscopy for Rapid Hydrogen Detection

Lifu Duan, Zhile Yuan, Zhidan Zheng, Weilin Ye et autres

Rapid detection of hydrogen (H 2 ) is essential for industrial production and environmental monitoring. Beat frequency photoacoustic spectroscopy offers an inherent measurement speed of milliseconds but at the cost of sensitivity. To overcome this limitation, we propose a novel photoacoustic ringdown …
