摘要

•First report of nonlinear optical properties Ag@Au bimetallic nanoparticles using Hymenaea courbaril leaf extract.•Non-linear optical properties were investigated by thermal lens and Z-scan technique in CW regime.•The surface plasmon resonance band profile changes by varying the gold and silver ratio of the Ag@AuNPs.•Ag@AuNps exhibited an increase in thermal diffusivity and reverse saturable nonlinear absorption.
