Structural and optical properties of DCM thin films prepared by PVD

In the present work, thin films of 4-(dicyanomethylenes)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM) were successfully grown on glass substrates using the vacuum evaporation technique in a high vacuum. These thin layers were cultivated on a glass substrate cleaned by an ultrasound bath. The atomic force microscopy was used for the surface analysis of the thin films. The evolution, roughness, and distribution of the surface structure are also measured by using the Minkowski functional procedure. UV-visible spectroscopy was used to study the transmittance and the absorbance of DCM thin films. In addition, the study also included gape energy which was studied using the tauc plot method.
