Abstract

Stable nanosized germanium particles were synthesized in a liquid medium (acetone) by laser irradiation of single-crystal germanium plates under aerobic and anaerobic conditions at room temperature. Various experimental methods—optical spectrophotometry, atomic force microscopy, and dynamic light scattering—made it possible to detect stable nanosized Ge particles in acetone and record optical absorption and luminescence spectra depending on the time of laser irradiation in the presence and absence of oxygen. Particular attention is paid to the results of the effect of laser irradiation on the physicochemical properties of pure acetone.
