Characterization, film optical properties

Our group initially reported that the average deposition ratio of 7(A) (down stroke) was about 0.5 to 0.7, and the average transfer ratio of 8(B) (up stroke) was about 0.9 to 1.5 (70). Recently, it was found that if the Langmuir films are replaced after only about 50% is consumed in the dipping process (compared to about 90% in the first case), transfer ratios were always between 0.95 and 1.0. Work is presently underway to characterize the optical properties of new bilayer films prepared with transfer ratios close to unity.

In Section 2.4, the main aspects of the nitrogen-induced structural changes are presented, by the discussion of the most important characterization techniques. This presentation is complemented by an overview of a-C(N) H structure. Finally, in Sections 2.5 and 2.6, respectively, results concerning the mechanical properties, and the electrical and optical properties of a-C(N) H films are presented. As long as possible, they will be correlated with the observed structure changes.

Nonlinear optical techniques are extremely useful in characterizing the chiral properties of materials, as is pointed out by Verbiest and Persoons in Chapter 9. These authors give an in-depth discussion of this tool, both from an experimental and theoretical point of view, paying special attention to the characterization of chiral surfaces and thin films. In the second part of their contribution they highlight the role chiral materials can play in the field of nonlinear optics and photonics, which opens the way for a variety of applications. 

The patterned and non-pattemed phosphor films show similar optical properties. So all the characterizations for the optical properties were performed on the non-pattemed films due to their relatively easy availability.
