Abstract

Features of nonlinear refraction formation in colloidal solutions containing Ag2S quantum dots passivated with thioglycolic acid (Ag2S/TGA QDs) with a concentration of 0.1% and an average size of 2.0 nm are considered. Nonthermal self-focusing caused by the “band filling” effect under exciton excitation was detected by the Z-scanning method for 10-ns pulses of a YAG:Nd laser at a wavelength of 532 nm for Ag2S/TGA QDs having an exciton absorption maximum at 590 nm.
