Abstract
Perylene tetracarboxylic Dianhydride (PTCDA) is a chemically stable organic semiconductor precursor widely used in optoelectronic research. This work investigates the fabrication and characterization of PTCDA thin films doped with europium-doped ���� ����2��4 with the goal of producing composite films exhibiting enhanced electrical and optical properties relative to pure PTCDA. Thin films were prepared through solution processing and drop-casting, followed by controlled thermal or ambient evaporation. The structural and chemical characteristics of the films were examined using UV–VIS spectroscopy, Fourier-Transform Infrared (FTIR) spectroscopy, optical microscopy, and X-ray diffraction (XRD). These techniques were used to evaluate changes in absorbance behavior, vibrational modes, microstructure, and crystallinity resulting from the incorporation of ���� ����2��4. The data collected indicate that the two materials interact within the composite films, producing measurable modifications to both the optical and vibrational signatures. These findings suggest that PTCDA:���� ����2��4 composites may offer a viable pathway toward tuning the electronic properties of PTCDA-based thin films.
