| 1 | A CaS:Ce,Sm-based dosimeter for online dosimetry measurement显示文摘A film dosimeter based on optically stimulated luminescence (OSL) material of CaS:Ce,Sm was developed for online irradiation dosimetry measurement.The stimulation is provided by a laser with a wavelength of 980 nm,and the OSL luminescenceis collected by a photodiode.Using 60Co γ-rays,we investigated the dosimetry characteristic of the dosimeter at different dose rates and total doses.The real-time detection results showed that the OSL signals versus total ionizing dose exhibited a good linearity in a dose range of 0.1-185 Gy. | SUN Yurun CHEN Zhaoyang FAN Yanwei YAN Shiyou HE Chengfa | 2011 | Nuclear Science and Techniques2011，22，2： | 3 |
| 2 | 1064 nm InGaAsP multi-junction laser power converters显示文摘Laser photovoltaic devices converting 1064 nm light energy into electric energy present a promising prospect in wireless energy transmission due to the commercial availability of high power 1064 nm lasers with very small divergence. Besides their high conversion efficiency, a high output voltage is also expected in a laser energy transmission system. Meanwhile,1064 nm InGaAsP multi-junction laser power converters have been developed using p^+-InGaAs/n^+-InGaAs tunnel junctions to connect sub-cells in series to obtain a high output voltage. The triple-junction laser power converter structures are grown on p-type InP substrates by metal-organic chemical vapor deposition(MOCVD), and InGaAsP laser power converters are fabricated by conventional photovoltaic device processing. The room-temperature I–V measurements show that the 1 × 1 cm^2 triplejunction InGaAsP laser power converters demonstrate a conversion efficiency of 32.6% at a power density of 1.1 W/cm^2, with an open-circuit voltage of 2.16 V and a fill factor of 0.74. In this paper, the characteristics of the laser power converters are analyzed and ways to improve the conversion efficiency are discussed. | Jiajing Yin Yurun Sun Shuzhen Yu Yongming Zhao Rongwei Li Jianrong Dong | 2020 | Journal of Semiconductors2020，41，6： | 1 |
| 3 | Characterizations of high-voltage vertically-stacked GaAs laser power converter显示文摘Six-junction vertically-stacked Ga As laser power converters(LPCs) with n^+-Ga As/p^+-Al0.37 Ga0.63 As tunnel junctions have been designed and grown by metal-organic chemical vapor deposition for converting the power of 808 nm lasers. The LPC chips are characterized by measuring current–voltage(I–V) characteristics under 808 nm laser illumination, and a maximum conversion efficiency ηc of 53.1% is obtained for LPCs with an aperture diameter of 2 mm at an input laser power of 0.5 W. In addition, the characteristics of the LPCs are analyzed by a standard equivalent-circuit model, and the reverse saturation current, ideality factor, series resistance and shunt resistance are extracted by fitting of the I–V curves. | Jie Huang Yurun Sun Yongming Zhao Shuzhen Yu Kuilong Li Jianrong Dong Jiping Xue Chi Xue Yang Ye | 2018 | Journal of Semiconductors2018，39，9： | 1 |
| 4 | Modified room temperature solid-state synthesis of yttria-stabilized zirconia(YSZ) nano-powders for solid oxide fuel cells显示文摘High-performance solid oxide fuel cell(SOFC) is in urgent need of high-quality electrolyte powders with high reactivity and chemical uniformity.Here,8 mol% Y_(2)O_(3) doped ZrO_(2)(YSZ) nano-powders were synthesized by an improved solid-state reaction method at ambient temperature,and were applied to the fabrication of SOFC electrolytes.YSZ nano-powders show average grain sizes of ^(2)0 nm and high dispersibility,which is comparable with or even better than some other chemical methods.Benefitting from their high reactivity,dense YSZ electrolytes(relative density of 97.9%) can be obtained at a relatively low sintering temperature of 1400℃.The optimized electrical conductivity reaches up to a high value of0.034 S/cm at 800 0C in air.The anode supported single cell with the construction of Ni-YSZ/YSZ/Sm_(0.2)Ce_(0.8)O_(2-δ)(SDC)/La_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-δ)(LSCF) exhibits the peak power density of 0.827 W/cm^(2) at800℃ while taking wet H_(2) as fuels and ambient air as oxidants. | Xiaoqian Xu Yurun Feng Zhaoyu Zhong Xue Guo Zhenhao Zhang Jiao Li Shikai Zhao Shigang Wu Haibin Sun | 2023 | Journal of Rare Earths2023，41，9： | 0 |
| 5 | Four-junction AlGaAs/GaAs laser power converter显示文摘Four-junction AlGaAs/GaAs laser power converters (LPCs) with n^+-Ga As/p^+-Al_(0.37)Ga_(0.63)As hetero-structure tunnel junctions (TJs) have been designed and grown by metal-organic chemical vapor deposition(MOCVD) for converting the power of 808 nm lasers. A maximum conversion efficiency ηc of 56.9% ± 4% is obtained for cells with an aperture of 3.14 mm^2 at an input laser power of 0.2 W, while dropping to 43.3% at 1.5 W.Measured current–voltage (I–V) characteristics indicate that the performance of the LPC can be further improved by increasing the tunneling current density of TJs and optimizing the thicknesses of sub-cells to achieve current matching in LPC. | Jie Huang Yurun Sun Yongming Zhao Shuzhen Yu Jianrong Dong Jiping Xue Chi Xue Jin Wang Yunqing Lu Yanwen Ding | 2018 | Journal of Semiconductors2018，39，4： | 0 |
