Structural characterization of lead sulfide thin films by means of X-ray line profile analysis

[摘要] X-ray diffraction patterns of chemically deposited lead sulphide thin films have been recorded and X-ray line profile analysis studies have been carried out. The lattice parameter, crystallite size, average internal stress and microstrain in the film are calculated and correlated with molarities of the solutions. Both size and strain are found to contribute towards the broadening of X-ray diffraction line. The values of the crystallite size are found to be within the range from 22â€�??33 nm and the values of strain to be within the range from 1.0 Ã�? 10^-3â€�??2.5 Ã�? 10^-3.
