Özet:

 

PbO-PbS thin films were deposited on glass substrates using the chemical  bath deposition (CBD) technique. PbO thin films were deposited from the  solution of lead nitrate (Pb(NO3)2) and sodium hydroxide (NaOH).  Ethylenediaminetetraacetate (EDTA) served as the complexing agent. Some of  the PbO films were used as substrate for the deposition of PbS. The PbS was  deposited from alkaline solution of lead nitrate and thioacetamide.  Triethanolamine was used as the complexing agent. Some of the films were  subjected to thermal treatment after deposition.     Energy dispersive X-ray fluorescence analysis confirmed the presence of Pb  and S in the PbS thin films, while Rutherford backscattering was used to  identify the composition of PbO thin films.     The absorbance of PbO-PbS films was extremely high in the UV region and  decreased exponentially with increase in wavelength. The transmittance  increased sharply but almost linearly with wavelength from the mid-vis  region, having a maximum percentage value of 21% at 1000 nm (NIR). Hence,  PbO-PbS films are good materials for UV filters and glazing for creating  warmth in rooms.    The band gap of PbO-PbS films is in range 2.15-2.25 eV.
