Femtosecond Pulsed Fiber Laser Based on Graphdiyne-Modified Tapered Fiber

Nanomaterials, 2022
We report the application of saturable absorbers prepared from graphdiyne-modified tapered fibers to an erbium-doped fiber laser to achieve a femtosecond pulse output. Graphdiyne quantum dots are successfully prepared by the Glaser–Hay method.

Graphdiyne Electrochemistry: Progress and Perspectives

Small, 2022
AbstractGraphdiyne, a carbon allotrope, was synthesized in 2010 for the first time. It consists of two acetylene bonds between adjacent benzene rings. Graphdiyne and its composites thus exhibit ultrahigh intrinsic electrochemical activities. As “star” electrode materials, they have been utilized for various electrochemical applications. With the aim of
