SYNTHESIS AND CHARACTERIZATION OF LEAD OXIHYDROXYCARBONATETHIN FILMS

In this work we studied a new material thin film basedin a modification for lead sulfide thin films formulation. The characterizations were: optical microscopy of the surface, where can be observed certain homogeneity at large scale, surface morphology by Scanning Electron Microscopy, here we could to observe clusters of circulars and fibers shapes; surface profilometry was used to measure the film thickness giving a value of 13.67µm. Top and perspective views of Atomic Force Microscopy reveal us the formation of fibrillated aggregates, X-rays Photoelectrons Spectrum show to us the chemical composition of the material thin film, with this analysis we could to observe the cleanness of the chemical bath deposition technique, because only were present lead, oxygen and the carbon elements, those that are hoped. Finally we determine the energy band gap from the absorption, with the value of 3.32 eV. (Received January 5, 2014; Accepted March 13, 2014)
