Je diskutován mechanismus vazeb mezi organickými rezidui a anorganickou matricí - interakce mezi S ionty a amínovými klastry.
eng	Structural features of spin-coated thin films of binary AsxS100-x chalcogenide glass system	Spin-coating technology offers a convenient method for fabricating photostable chalcogenide glass thin films that are especially attractive for applications in IR optics. In this paper we report the structure of spin-coated AsxS100 (-) (x) (x = 30, 35, 40) thin films as determined using high resolution X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy, especially in relation to composition (i.e. As/S ratio) and preparation process variables. It was observed that As atoms during preparation have a tendency to precipitate out in close to stoichiometric compositions. The mechanism of bonding between the inorganic matrix and organic residuals is discussed based on the experimental data. A weak interaction between S ions and amine-based clusters is proposed as the basis of structural organization of the organic-inorganic interface.
