Unraveling the Synthesis, Characterization, and Optical Behaviors of Thin Films: a Comprehensive Study

Abstract

Thin films have significant importance both in academia and industry due to their unique properties and wide range of applications in electronic devices, solar cells, sensors, flat panel displays, and more. The current study aimed to synthesize and characterize polymers that exhibit semiconductor behavior and investigate their potential use in optoelectronic devices. For this purpose, thin films were prepared from the synthesized polymers. The optical properties of thin films with thicknesses of 23 mu m and 4 mu m were measured using UV-Vis spectroscopy, and the Eg values were found to be 1.30 eV and 2.16 eV, respectively. Results indicated that the obtained values of the optical bandgap energy and refractive index of the thin films suggested that they can be promising materials for the fabrication of optoelectronic devices such as solar cells, sensors, and light-emitting diodes. The observed dependence of these properties on the thickness of the films also suggested that their performance can be tuned by controlling their deposition parameters. Overall, these results demonstrated the potential of thin films as versatile building blocks for various applications in the fields of photonics and electronics.
