R. Kellner et al., FTIR-MICROSPECTROSCOPIC DETECTION OF ULTRA-THIN ORGANIC FILMS ON CHALCOGENIDE FIBERS, Fresenius' journal of analytical chemistry, 346(6-9), 1993, pp. 612-614
In this paper the discovery is presented that FTIR microspectroscopy i
s also suitable for the micro-analysis of very thin organic layers in
the range of 3.6 to 36 nm on chalcogenide fibers. Theoretical confirma
tion using the ray-tracing method is given and the observation of ultr
a-thin coatings on fibers is made possible by a signal enhancement com
pared to planar substrates due to the geometry of the fiber.
