Embedded gold nanoparticles in TiO2 crystal for photonic applications
Materials Letters(2022)
摘要
•Plasmonic Au nanoparticles are synthesized in TiO2 crystal by ion implantation.•Third-order optical nonlinearity tailoring is achieved through charge transfer between Au nanoparticles and TiO2.•Enhanced modulation depth and optimized saturation intensity suggest significant potential photonic applications.
