Visible‐Light‐Excited Optical Thermometry in Ca3Sc2Si3O12: Er3+ via an Efficient Eu2+ Bridge
ABSTRACT Er3+ ions are promising for optical thermometry due to their thermally coupled levels. However, their parity‐forbidden transitions result in weak and narrowband absorption, which restricts excitation to infrared lasers (e.g., 808, 980, or 1550 nm). Moreover, the single emission center inherently limits temperature sensitivity. In this work, we

精确的恒星星等信息是开展导航星表建立、航天器定姿、红外相机定标等工作的基础,现有公开星表涵盖测光波段不全且带宽普遍较窄,难以找到与任务传感器响应波段相匹配的星等信息。为此提出了一种基于恒星辐射光谱的传感器响应波段星等计算方法。该方法利用公开星表数据信息,建立星表测光波段与传感器响应波段星等差值模型,对星表星等与传感器响应波段星等差值进行估算;将色指数计算的恒星近似表面温度作为先验信息,在传感器响应波段区间进行普朗克方程求解,进而推算恒星在传感器响应波段的星等。星表数据计算验证表明 ...

ABSTRACT Reliable monitoring of ultraviolet (UV) radiation is critical for protecting human health, yet existing sensors often rely on costly or rigid components that hinder portability. Here we report a wearable, low‐cost colorimetric sensor for quantitative UV dosimetry, enabled by radical‐triggered aggregation of gold nanoparticles (AuNPs).

Tracking with GPS and accelerometers shows that great evening bats in subtropical China use two overwintering strategies: some remain in continuous hibernation, while others switch between torpor and activity as temperatures change. This behavioral flexibility, shaped by climate, underscores the importance of protecting diverse roosting habitats for ...

ABSTRACT The precise quantification of cytokines is crucial for monitoring disease onset and progression. Herein, we developed a synergistic signal amplification approach by utilizing nanoreactor‐encapsulated CeO2 nanozymes, which were in situ electrodeposited within the mesoporous silica nanochannel film (SNF) grown on indium tin oxide (ITO ...
