IntroductionRaman scattering is a powerful nondestructive technique that gives vibrational information about organic and inorganic materials. Raman scattering features, such as intensity, frequency and width, are strongly dependent on compositions, defects, short-range orders, crystal structures, and internal stresses of materials. Therefore, it has been widely used to obtain detailed information about the structural properties of semiconductors, high-Tc superconductors, ceramics, catalysts, carbon based materials, and Ⅲ-Ⅴ valent metallic nitride materials, including lattice perfection, strain, crystalline, interface, and compositional uniformity[1].
