Abstract: The main objective of this paper is the realization and characterization of a new organic thin film semiconductor material through the use of an ideal mixture of Acetaminophen/Curcumin utilizing several characterization techniques. From optical analysis, we can conclude that our semiconductor material is comparable and shows good concurrency to the semiconductors applied in technologic applications. In fact, the analysis of the optical measurement (transmittance T) conducting to the optical energy bandgap, Eg, it was found the optical bandgap is around to 2.6±0.02eV. In addition, by using the Wemple Didominico model it was found the dispersion energy ED varied from 5eV to 7eV, the average bandgap EM separated the center of both bands occupied and unoccupied is around 4.5eV and the static refractive index n0 varies from 1.3 to 2 and it dependent on the compactness and transparency of the material.
