In modern material science and material technology the accurately defined structuring of known solid down to microscopically controlled dimensions is now becoming more important than the continual search for new chemical compound. This trend is most obvious in the domain of semiconductor research and development. Metal chalcogenides form an important class of inorganic materials, which include several technologically important applications. The design of metal chalcogenides is of technological interest and has encouraged recent research. Raman scattering spectroscopy is a powerful, non-destructive procedure, sensitivity to local environment. High¿pressure Raman spectroscopy is one of the most useful techniques to investigate the changes that matter undergoes under external pressure. Valuable information about intermolecular interactions, structural changes, phase transitions, and molecular vibrations can be obtained from Raman spectroscopy. Looking to the above aspect, in the present work pressure and temperature dependent Raman spectroscopy was used to study the vibrational properties of metal chalcogenides single crystals.
