Abstract The Raman spectra of CdS 1− x Se x 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.
