Studying the optical properties of epoxy panel doped with al-anthedin dye

In this work the luminescent solar concentrators (LSC) plates doped with Al-Anthedin dye was prepared by at the solid state laboratory at room temperature with different thicknesses and concentrations .The Anthedin dye concentrations were (1×10-4, 2×10-4and 3×10-4) mol/L. The optical characteristics have been studied such as absorption and energy gap also the optical constants such as the absorption coefficient and extinction coefficient were calculated for all panels. Increasing the concentration of the Al-Anthedin dye led to increase the values of absorbance, absorption and extinction coefficient. The results also demonstrate that the value of the energy gap was decreased with increasing the concentrations from (2.2eV) for the lowest concentration to (2.1eV)for the highest one.
