| Abstract Scope |
Additive manufacturing is one of the hottest topic in the modern era. Printed chalcogenide glass films have added a new dimension in some specific applications like space exploration, nuclear industry and others. In this work, we report about the structural changes of printed GexSe100-x chalcogenide films under UV light irradiation. The effect of the different irradiation doses on printed films results in creation of dangling bonds and other materials changes. Accelerated oxidation of the chalcogenide matrix is found out, which specifically affects the Ge rich films. A number of compositions of printed GexSe100-x chalcogenide films were studied applying Raman spectroscopy at different discrete UV irradiation doses to analyze the structural changes. AFM studies revealed the changes in the surface roughness of printed films. This effect shows a close dependence upon the exposed dose. The molecular composition and the phase identification of the printed films using XRDare studied as well. |
