Abstract:
Actually, the doped polymers may present useful applications in integrated optics or in real time holography. In order to tailor materials with improved proprieties within the doped polymer class, it is necessary to understand and control the electronic mechanisms involved in the optical behavior.
Electronic mechanism responsible for the optical behavior under the UV exposure of the mixed Fe-Sb and Sn doped polymers were studied in comparison with the correspondent mono doped ones.
Optical absorption as well as Mossbauer measurement was perfomed on different UV exposed films. The new data provided the role of each element from the pair on the involved electronic mechanism induced by irradiation.
