摘要：

Mesoporous hexagonally ordered SiO2 (SBA-15) with a pore diameter of 7 nm was used as a host matrix for nanoparticles of amorphous and crystalline germanium. Raman spectra were recorded for these germanium nanoparticles and for bulk amorphous and crystalline germanium powder. The band shifts and line shapes of the Raman bands for the optical phonon at similar to300cm(-1) were analyzed and compared to the theoretical predictions derived from the phonon confinement model. In addition, the microstructure of amorphous hydrogenated germanium could be further elucidated by Raman spectroscopy and by thermal analysis.
