Optical Thermometry Based on Up‐Conversion Luminescence Behavior of Er3+ ‐Doped Transparent Sr2YbF7 Glass‐Ceramics

10-Aug-2015 | XiaoMan Li, JiangKun Cao, YunLe Wei, ZhiRong Yang, Hai Guo, Journal of the American Ceramic Society, 2015

Transparent novel glass‐ceramics containing Sr2YbF7:Er3+ nanocrystals were successfully fabricated by melt‐quenching technique. Their structural and up‐conversion luminescent properties were systemically investigated by XRD, HRTEM, and a series of spectroscopy methods. The temperature‐dependent ...

Sensors, Vol. 15, Pages 18579-18586: Multi-Stress Monitoring System with Fiber-Optic Mandrels and Fiber Bragg Grating Sensors in a Sagnac Loop

29-Jul-2015 | Kim, Hyunjin ; Sampath, Umesh ; Song, Minho, Sensors, 2015

Fiber Bragg grating sensors are placed in a fiber-optic Sagnac loop to combine the grating temperature sensors and the fiber-optic mandrel acoustic emission sensors in single optical circuit. A wavelength-scanning fiber-optic laser is used as a common light source for both sensors. A fiber-optic ...

Sensors, Vol. 15, Pages 17232-17240: On-Chip Sensing of Thermoelectric Thin Film’s Merit

16-Jul-2015 | Xiao, Zhigang ; Zhu, Xiaoshan, Sensors, 2015

Thermoelectric thin films have been widely explored for thermal-to-electrical energy conversion or solid-state cooling, because they can remove heat from integrated circuit (IC) chips or micro-electromechanical systems (MEMS) devices without involving any moving mechanical parts. In this paper, ...

Thermal imaging using polymer nanocomposite temperature sensors

30-Jun-2015 | Elizabeth Sauerbrunn, Ying Chen, Jeffrey Didion, Miao Yu, Elisabeth Smela, Hugh A. Bruck, physica status solidi (a), 2015

Sensing temperature distributions over an area is of interest for many applications, and it is currently performed using sensors that are attached to the structure. In this work a conductive “smart paint”, made from latex and exfoliated graphite, is introduced for temperature sensing. This ...

Highly Sensitive Optical Thermometry of Yb3+‐Er3+ Codoped AgLa(MoO4)2 Green Upconversion Phosphor

18-Jun-2015 | Ting Li, Chongfeng Guo, Shaoshuai Zhou, Changkui Duan, Min Yin, Journal of the American Ceramic Society, 2015

Er3+–Yb3+ codoped AgLa(MoO4)2 phosphors with intense green emission from 2H11/2/4S3/2 → 4I15/2 transitions and negligible red emission from 4F9/2 → 4I15/2 transition of Er3+ were synthesized by sol–gel process. Its temperature sensing performance was evaluated based on the temperature dependence ...

Optical Temperature Sensing Behavior of High‐Efficiency Upconversion: Er3+–Yb3+ Co‐Doped NaY(MoO4)2 Phosphor

08-May-2015 | Xingxing Yang, Zuoling Fu, Yanmin Yang, Chunpeng Zhang, Zhijian Wu, Tianqi Sheng, Journal of the American Ceramic Society, 2015

A class of Yb3+/Er3+ co‐doped NaY(MoO4)2 upconversion (UC) phosphors have been successfully synthesized by a facile hydrothermal route with further calcination. The structural properties and the phase composition of the samples were characterized by X‐ray diffraction (XRD). The UC luminescence ...

Sensors, Vol. 15, Pages 10048-10058: A Resonant Pressure Microsensor Capable of Self-Temperature Compensation

29-Apr-2015 | Li, Yinan ; Wang, Junbo ; Luo, Zhenyu ; Chen, Deyong ; Chen, Jian, Sensors, 2015

Resonant pressure microsensors are widely used in the fields of aerospace exploration and atmospheric pressure monitoring due to their advantages of quasi-digital output and long-term stability, which, however, requires the use of additional temperature sensors for temperature compensation. This ...

Hybridized Electromagnetic–Triboelectric Nanogenerator for Scavenging Air-Flow Energy to Sustainably Power Temperature Sensors

08-Apr-2015 | Xue Wang; Shuhua Wang; Ya Yang; Zhong Lin Wang, ACS Nano, 2015

We report a hybridized nanogenerator with dimensions of 6.7 cm × 4.5 cm × 2 cm and a weight of 42.3 g that consists of two triboelectric nanogenerators (TENGs) and two electromagnetic generators (EMGs) for scavenging air-flow energy. Under an air-flow speed of about 18 m/s, the hybridized ...
