, two-dimensional (2D) materials are now venturing and excelling in yet another arena of ultrafast photonics, a rapidly developing field encompassing a large range of important applications including optical modulation through optical limiting/mode-locking, photodetectors, optical communications, integrated miniaturized all-optical devices and so on. Our group has been devoted to building the arsenal of 2D materials with large third-order nonlinearities, including transition metal dichalcogenides (TMDs), carbon nitride, single-element materials from Group 15, 2D hybrids and vdW heterostructures. In particular, we explore their origin of nonlinear optical responses from the aspect of excited state dynamics using time-resolved spectroscopic techniques such as femtosecond transient absorption spectroscopy. In this review, we propose the roadmap for screening 2D materials for ultrafast photonics through focusing on the third-order nonlinear optical properties of 2D materials and corresponding applications, and then performing mechanistic investigations
via
time-resolved spectroscopy and calculations, which in turn provide feedback to further guide the fabrication of 2D materials. We offer our own insights on the future trends for the development and theoretical calculations of 2D materials/devices in the final part of

| Bibliography: | Xin-Ping Zhai received her master's degree in physical chemistry from Lanzhou University. She is currently pursuing her PhD degree in physical chemistry in Lanzhou University under the supervision of Prof. Qiang Wang. Her interests are focused on optoelectronic properties of 2D materials. Qiang Wang received a BS degree from Wuhan University in 1999. He then joined Prof. Yi Chen's group at the Institute of Chemistry, Chinese Academy of Sciences as a graduate student and performed research in the field of Capillary Electrophoresis (CE) and spectroscopic analysis. He got his MS degree in the year of 2002. He thereafter went to Boston University in the USA to pursue a PhD degree in Prof. Rosina Georgiadis' group, developing novel label-free detection methods based on surface plasmon resonance (SPR). He transferred to Boston College in 2004 and worked on ultrafast time-resolved spectroscopy under the guidance of Prof. Torsten Fiebig. The main topics were focused on the DNA photonics study on the femtosecond time scale, photoinduced electron and energy transfer processes in DNA upon photon excitation. He obtained his PhD degree in May, 2008 and became an associate professor of chemistry at Lanzhou University in October. He was promoted to a full professorship in 2017. His current research interests include nonlinear optics and ultrafast spectroscopy. Hao-Li Zhang received his BS in organic chemistry in 1994, and PhD degree in 1999 from Lanzhou University. He then worked in the University of Leeds and Oxford University as a postdoc. In 2004, he was appointed as a full professor by the State Key Laboratory of Applied Organic Chemistry (SKLAOC) of Lanzhou University. He is currently the deputy director of SKLAOC and Deputy Dean of the College of Chemistry and Chemical Engineering. In 2014, he became a Fellow of Royal Society of Chemistry (FRSC). He is an editorial board member of Acta Physico-Chimica Sinica and Chinese Chemical Letters, and an advisory board member of Chem. Soc. Rev. Prof. Hao-Li Zhang is interested in developing new organic functional materials for electronic and optoelectronic applications. He has published more than 240 research papers on peerreviewed international journals with citation over 5000, his H index is 37. Current research projects include: design and synthesis of organic semiconductors; novel light emitting materials; nonlinear optical materials; molecular electronics; novel organic/inorganic hybrid materials for advanced optoelectronics. Bo Ma is currently pursuing his PhD degree in material science and engineering in Lanzhou University under the supervision of Prof. Qiang Wang. His interests are focused on optoelectronic properties of 2D materials. ObjectType-Article-1 SourceType-Scholarly Journals-1 ObjectType-Feature-2 content type line 14 content type line 23 |
