| 1 | Enhanced photodetector performance of black phosphorus by interfacing with chiral perovskite显示文摘Heterogeneous stackings of two-dimensional(2D)semiconductors and halide perovskites have attracted much attention owing to their respective superior optoelectronic properties.Black phosphorus(BP),as a unique 2D member with narrow bandgap,high mobility,and strong anisotropy,has never been combined with 2D layered perovskites.Herein,we construct a new BP-based van der Waals heterostructure combing with 2D chiral hybrid perovskite(i.e.,(MBA)_(2)PbI_(4))for promoting the performance and enriching the functionalities of BP.A series of BP characteristics,including carrier mobility,photoresponsivity,and polarization sensitivity,are synergistically enhanced when interfacing with(MBA)_(2)PbI_(4).For instance,the photodetector responsivity and photogain of BP in heterostructures are boosted by almost one order of magnitude with respect to BP alone,which is more obvious under excitation above the bandgap of perovskite.This is because the interfacing perovskite provides an inflow of numerous photogenerated carriers to BP,to reinforce the charge carrier transfer,separation,and transport processes.Additionally,the ability of both linearly and circularly polarized photodetection can be integrated into the BP/(MBA)_(2)PbI_(4)heterostructure.Our work sheds new insight on the heterostructure assembly for promising optoelectronic applications within 2D materials and perovskite families. | Yang Cao Congzhou Li Jie Deng Tong Tong Yuchi Qian Guixiang Zhan Xu Zhang Kaiyue HeHuifang Ma Junran Zhang Jing Zhou Lin Wang | 2022 | Nano Research2022，15，8： | 0 |
| 2 | Add-on plasmonic patch as a universal fluorescence enhancer显示文摘Fluorescence-based techniques are the cornerstone of modern biomedical optics,with applications ranging from bioimaging at various scales(organelle to organism)to detection and quantification of a wide variety of biological species of interest.However,the weakness of the fluorescence signal remains a persistent challenge in meeting the ever-increasing demand to image,detect,and quantify biological species with low abundance.Here,we report a simple and universal method based on a flexible and conformal elastomeric film with adsorbed plasmonic nanostructures,which we term a“plasmonic patch,”that provides large(up to 100-fold)and uniform fluorescence enhancement on a variety of surfaces through simple transfer of the plasmonic patch to the surface.We demonstrate the applications of the plasmonic patch in improving the sensitivity and limit of detection(by more than 100 times)of fluorescence-based immunoassays implemented in microtiter plates and in microarray format.The novel fluorescence enhancement approach presented here represents a disease,biomarker,and application agnostic ubiquitously applicable fundamental and enabling technology to immediately improve the sensitivity of existing analytical methodologies in an easy-to-handle and cost-effective manner,without changing the original procedures of the existing techniques. | Jingyi Luan Jeremiah J.Morrissey Zheyu Wang Hamed Gholami Derami Keng-Ku Liu Sisi Cao Qisheng Jiang Congzhou Wang Evan D.Kharasch Rajesh R.Naik Srikanth Singamaneni | 2018 | Light(Science & Applications)2018，7，1： | 0 |
| 3 | Voxel modeling and association of ubiquitous spatiotemporal information in natural language texts显示文摘The ubiquitous spatiotemporal information extracted from Internet texts limits its application in spatiotemporal association and analysis due to its unstructured nature and uncertainty.This study uses ST-Voxel modeling to solve the problem of structured modeling and the association of ubiquitous spatiotemporal information in natural language texts.It provides a new solution for associating ubiquitous spatiotemporal information on the Internet and discovering public opinion.The main contributions of this paper include:(1)It proposes a convolved method for ST-Voxel,which solves the voxel modeling problem of unstructured and uncertain spatiotemporal objects and spatiotemporal relation in natural language texts.Experiments show that this method can effectively model 5 types of spatiotemporal objects and 16 types of uncertain spatiotemporal relation founded in texts;(2)It realizes the unknown event discovery based on voxelized spatiotemporal information association.Experiments show that this method can effectively solve the aggregation of ubiquitous spatiotemporal information in multi-natural language texts,which is conducive to discovering spatiotemporal events.The selection of convolution parameters in voxel modeling is also discussed.A parameter selection method for balancing the discovery capability and discovery accuracy of spatiotemporal events is given. | Dali Wang Xiaochong Tong Chenguang Dai Congzhou Guo Yi Lei Chunping Qiu He Li Yuekun Sun | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
