Abstract

Nanocrystalline PbS thin films were prepared by Chemical Bath Deposition (CBD) at 40 ± 2°C onto glass substrates and their structural and optical properties modified by in-situ doping with Hg. The morphological changes of the layers were analyzed using SEM and the X-rays spectra showing growth on the zinc blende (ZB) face. The grain size determined by using X-rays spectra for undoped samples was found to be~36 nm, whereas with the doped sample was 32–20 nm. Optical absorption spectra were used to calculate theEg, showing a shift in the range 1.4–2.4 eV. Raman spectroscopy exhibited an absorption band~135 cm−1displaying only a PbS ZB structure.
