Abstract

A solution synthesis of crystalline Ge nanoparticles (nc-Ge) is reported. The metathesis reaction of NaGe with excess GeCl4 in glyme solvents produces nc-Ge. Metathesis reactions between KGe and excess GeCl4 or GeCl2:(dioxane) in glyme and Mg2Ge and excess GeCl4 in diglyme and triglyme were also investigated. The surface of these nanoparticles is terminated with alkyl groups by reaction with alkyl Li and Grignard reagents. The alkyl-terminated crystalline Ge nanoparticles (R̂-nc-Ge) were characterized by Fourier transform infrared spectroscopy, high-resolution transmission electron microscopy, powder X-ray diffraction, UV-vis absorption spectroscopy, photoluminescence, and photoluminescence excitation spectroscopy. The optical properties of R̂-nc-Ge made by this method agree with predictions from quantum confinement models.
