| Abstract: | Lead sulfide (PbS) nano-structured film has been grown on quartz substrates by the PLD technique. The deposited films were
characterized by X-ray diffraction (XRD), selected area electron diffraction (SAED), transmission electron microscopy (TEM)
and scanning electron microscopy (SEM). Formation of cubic phase of PbS nanocrystals is proven. The absorption and emission
spectra were measured for different thicknesses of the films. I–V characteristics and photoconductivity of the deposited film were also measured. The results indicate an efficient performance
of the deposited films as an optical detector. |
