Synthesis and enhanced nonlinear optical properties of graphene/CdS organic glass

摘要

Graphene/CdS (G/CdS) nanocomposite was first fabricated by a hydrothermal method.G/CdS nanocomposite was then dispersed in polymethyl methacrylate (PMMA) for preparation of organic glass by a casting method.The G/CdS/PMMA organic glass exhibits enhanced nonlinear optical (NLO) properties compared to G/PMMA and CdS/PMMA organic glass.Moreover, NLO properties of the G/CdS/PMMA organic glass can be controlled by adjusting the addition amount of G/CdS nanocomposite in PMMA.Our results demonstrate that the G/CdS/PMMA organic glass is very promising for optical devices, such as optical limiters and optical switch.
