It has long been speculated that magnetars are the engine powering repeating bursts from FRB sources4-13, but no convincing evidence has been collected so far14. Recently, the Galactic magnetar SRG 1935+2154 entered an active phase by emitting intense soft íray bursts15. One FRB-like event with two peaks (FRB 200428) and a luminosity slightly lower than the faintest extragalactic FRBs was detected from the source, in association with a soft íray/hard-X-ray flare18-21. Here we report an eight-hour targeted radio observational campaign comprising four sessions and assisted by multi-wavelength (optical and hard-X-ray) data. During the third session, 29 soft-íray repeater (SGR) bursts were detected in íray energies. Throughout the observing period, we detected no single dispersed pulsed emission coincident with the arrivals of SGR bursts, but unfortunately we were not observing when the FRB was detected. The non-detection places a fluence upper limit that is eight orders of magnitude lower than the fluence of FRB 200428. Our results suggest that FRB-SGR burst associations are rare. FRBs may be highly relativistic and geometrically beamed, or FRB-like events associated with SGR bursts may have narrow spectra and characteristic frequencies outside the observed band. It is also possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.   Modeling and analysis of NWC signal propagation amplitude based on LWPC and IRI models 期刊论文  OAI收割 CHINESE JOURNAL OF GEOPHYSICS-CHINESE EDITION, 2019, 卷号: 62, 期号: 9, 页码: 3223-3234 作者:  Yi Juan;  Gu XuDong;  Li ZhiPeng;  Lin RenTong;  Cai YiHui   |  收藏  |  浏览/下载：49/0  |  提交时间：2020/05/18 NWC very low frequency (VLF) transmitter signals  Long Wavelength Propagation Capability (LWPC) model  International Reference Ionosphere (IRI) model  Communication and navigation   Preparation of Multicolor Photoluminescent Carbon Dots by Tuning Surface States 期刊论文  OAI收割 NANOMATERIALS, 2019, 卷号: 9, 期号: 4 作者:  Jiang, Kai;  Feng, Xiangyu;  Gao, Xiaolu;  Wang, Yuhui;  Cai, Congzhong   |  收藏  |  浏览/下载：120/0  |  提交时间：2019/12/18 GRAPHENE QUANTUM DOTS  FULL-COLOR EMISSION  LONG-WAVELENGTH  FLUORESCENCE  CHALLENGES  RED  LUMINESCENCE  MECHANISM  NANODOTS  GREEN   Ultra-broadband and high absorbance metamaterial absorber in long wavelength Infrared based on hybridization of embedded cavity modes 期刊论文  OAI收割 Optics Communications, 2019, 卷号: 448, 页码: 1-9 作者:  Y.Luo;  Z.Z.Liang;  D.J.Meng;  J.Tao;  J.Q.Liang   |  收藏  |  浏览/下载：22/0  |  提交时间：2020/08/24 Metamaterial absorbers,Long wavelength infrared,Embedded cavity modes,microbolometers,Optics   Long-wavelength chromophores with thermally activated delayed fluorescence based on fluorescein derivatives 期刊论文  OAI收割 JOURNAL OF PHOTONICS FOR ENERGY, 2018, 卷号: 8, 期号: 3, 页码: 12 作者:  Lu, Meiheng;  Song, Fengling;  Peng, Xiaojun;  An, Jing;  Wu, Yingnan   |  收藏  |  浏览/下载：42/0  |  提交时间：2019/06/20 long-wavelength  thermally activated delayed fluorescence  long lifetime  fluorescein derivatives   Long-wavelength chromophores with thermally activated delayed fluorescence based on fluorescein derivatives 期刊论文  iSwitch采集 Journal of photonics for energy, 2018, 卷号: 8, 期号: 3, 页码: 12 作者:  An, Jing;  Wu, Yingnan;  Lu, Meiheng;  Han, Keli;  Song, Fengling 收藏  |  浏览/下载：73/0  |  提交时间：2019/05/08 Long-wavelength  Thermally activated delayed fluorescence  Long lifetime  Fluorescein derivatives
