摘要：

Raman scattering at room temperature is reported in ZnS(x)Se1-x alloys for the range of 0 less-than-or-equal-to X less-than-or-equal-to 1. The optical phonon energies are varied as a function of x and subjected to asymmetric broadening. The asymmetric broadening of the spectra is explained by a "spatial correlation" model assuming spherical compositional clusters of which distribution is described by the Gaussian correlation function. The results demonstrate that Raman spectroscopy is a powerful tool to study the microscopic structure of the substitutional disorder.
