Size Controlled Synthesis of Germanium Nanocrystals: Effect of Ge Precursor and Hydride Reducing Agent

Figure 6

(a) Photoluminescence spectra of Ge NCs synthesised by reduction of GeCl₄ by the various hydride reducing agents. (b) PL spectra of Ge NCs synthesised with GeBr₄ under the same reaction conditions. (c) PL spectra of Ge NCs recorded at different excitation wavelengths. (d) PL peak position (blue triangles) and intensity (red circles) versus excitation wavelength.
