This research aims to study the optical properties of anthracene and Carbazole compounds. We aim to write a comprehensive introduction to the physical properties of chains of organic compounds similar to the properties of anthracene compounds and their internal structure. We will discuss the variable absorption coefficient values according to the infrared curves and compare them with UV VIS curves. The researchers turned their attention to the coherent and characteristic structure of anthracene derivatives, which are found as building blocks based on their auto luminescent properties. The researchers [1-2-20] studied the interaction between anthracenes, Carbazole, and light. These properties include photoemission mechanisms to Designing and manufacturing organic compounds with precise properties and concentrations that contribute to many practical applications in all aspects of life. Thus, we will discuss the photo physical and structural properties of some different types of compounds and their effect on the effectiveness of light absorption, including their cohesion ability of different types of compounds for a number of samples studied in the laboratory. In this paper, we will review the most important photoelectric properties, the structure of anthracene and Carbazole compounds, and their X-ray diffraction to explore their fine structure. The results of exposing the surfaces of the samples to ultraviolet and infrared rays revealed that the absorption coefficient increases with increasing the number of strokes, and thus leads to an increase in the efficiency of the samples for use as light-emitting diodes.
