摘要：
Freestanding Ge/SiO2 core/shell nanoparticles were synthesized via metastable SiO2 hollow nanospheres by atmospheric-pressure thermal chemical Vapor deposition (APCVD) using SiCl4 and GeCl4 source gases. The Ge-core and. SiO2-shell thicknesses could be controlled by adjusting the annealing time and the source gas ratio. These-nanoparticles might be useful as labeling markers for fluorescent applications.
