Nonlinear optics of graphdiyne

Abstract

Graphdiyne (GDY), as a rising star of all-carbon materials, features a high degree of π-conjugation, uniformly distributed pores, and an intrinsic natural bandgap. These characteristics guarantee a large optical refractive index, low saturation intensity, and broadband absorption, which promises a wide range of application prospects in the field of nonlinear optics (NLO). In recent years, research on GDY in the field of NLO has become increasingly prevalent. In this review, we discuss the research progress on GDY in the domain of NLO. The corresponding bottlenecks and challenges for the future development of GDY in NLO are discussed.
