Nonlinear optical properties of near-infrared region Ag2S quantum dots pumped by nanosecond laser pulses [PDF]

Beilstein Journal of Nanotechnology, 2015
This study investigates near-infrared region Ag2S quantum dots (QDs) and their nonlinear optical response under 532 nm nanosecond laser pulses. Our experimental result shows that nonlinear transmission is reduced from 0.084 to 0.04.
