摘要：
The Raman spectra of CdS1-xSex nanocrystals, embedded in a borosilicate glass matrix, are studied, CdS-like and CdSe-like LO phonon frequencies being used to determine the nanocrystal composition. The Raman lineshape is analyzed taking account of confinement-related phonons with nonzero wavevector, surface phonon modes, glass matrix pressure and disorder effects.
