Properties of X-ray diffraction and Raman scattering in PbSe, PbS and PbS0,5Se0,5 thin films
Structural properties of PbSe, PbS and PbS0.5Se0.5 thin films and mechanisms of combinational scattering of light from phonons were studied by X-ray diffraction and Raman spectroscopy methods. The results of X-ray diffraction show that the crystallite sizes found in the thin layers of the studied substances are in the order of nanometers and vary in the interval d~10.7 ÷ 30.8 nm. It was determined that the scattering bands of the PbSe0.5S0.5 sample with large nanoparticle sizes shift to the region of large wave numbers compared to the scattering bands observed in the region of low wave numbers.
期刊介绍:
Chalcogenide Letters (CHL) has the aim to publish rapidly papers in chalcogenide field of research and
appears with twelve issues per year. The journal is open to letters, short communications and breakings news
inserted as Short Notes, in the field of chalcogenide materials either amorphous or crystalline. Short papers in
structure, properties and applications, as well as those covering special properties in nano-structured
chalcogenides are admitted.
