All-inorganic CsPbBr3 perovskite quantum dots as a photoluminescent probe for ultrasensitive Cu2+ detection
Yongfeng Liu,Xiaosheng Tang,Tao Zhu,Ming Deng,Iroegbu Paul Ikechukwu,Wei Huang,Guolu Yin,Yongzhong Bai,Dingrong Qu,Xianbin Huang,Feng Qiu +10 more
TL;DR: In this paper, the photoluminescence (PL) intensity of CsPbBr3 PQDs is significantly quenched within several seconds after the addition of Cu2+ due to effective electron transfer from the PQD to the added Cu2+, which is experimentally verified via analyzing absorption spectra and PL decay lifetime.
Journal ArticleDOI
Nitrogen doped graphene quantum dots as a fluorescent probe for mercury(II) ions
Yongfeng Liu,Xiaosheng Tang,Ming Deng,Yulong Cao,Yujia Li,Hua Zheng,Fuhui Li,Fabin Yan,Tianyi Lan,Leilei Shi,Lei Gao,Ligang Huang,Tao Zhu,Hao Lin,Yongzhong Bai,Dingrong Qu,Xianbin Huang,Feng Qiu +17 more
TL;DR: A highly selective fluorescent probe for Hg2+ that consists of nitrogen doped graphene quantum dots (NGQDs) that are nearly spherical in shape, have an average diameter of 2.7 nm and excitation-independent emission and blue fluorescence is quenched by Hg1+ due to both dynamic and static quenching.
Journal ArticleDOI
80 km Fading Free Phase-Sensitive Reflectometry Based on Multi-Carrier NLFM Pulse Without Distributed Amplification
Jingdong Zhang,Haoting Wu,Hua Zheng,Jingsheng Huang,Guolu Yin,Tao Zhu,Feng Qiu,Xianbin Huang,Dingrong Qu,Yongzhong Bai +9 more
TL;DR: In this article, a single-ended long-range phase-sensitive optical time domain reflectometer (ϕ-OTDR) sensing system without optical amplification in the sensing fiber is proposed.
Journal ArticleDOI
Selective and sensitive detection of copper(II) based on fluorescent zinc-doped AgInS2 quantum dots
Yongfeng Liu,Tao Zhu,Ming Deng,Xiaosheng Tang,Shuai Han,Anping Liu,Yongzhong Bai,Dingrong Qu,Xianbin Huang,Feng Qiu +9 more
TL;DR: In this article, hydrophobic zinc-doped AgInS2 (AIZS) quantum dots (QDs) are synthesized by hot-injection method, and then transferred into water-dispersible by sodium dodecyl sulfate (SDS) via mini-emulsion/solvent evaporation technique.
Journal ArticleDOI
Distributed fiber sparse-wideband vibration sensing by sub-Nyquist additive random sampling.
Jingdong Zhang,Hua Zheng,Tao Zhu,Guolu Yin,Min Liu,Yongzhong Bai,Dingrong Qu,Feng Qiu,Xianbing Huang +8 more
TL;DR: In this article, a sub-Nyquist additive random sampling (sNARS) method was proposed for a phase-sensitive optical time domain reflectometry (ϕ-OTDR) system.
