Popis: In this paper, alizarin yellow GG (AYGG) – CuCl2 doped with polyvinyl alcohol (PVA) has been successfully synthesized. This composite has spherical shape particles with amorphous structure. Thermal analysis indicates that there is an endothermic change, which is related to the glass transition. In addition, the coordination between the transition metal Cu(II) ion and AYGG (ligand) occurs via oxygen atoms of phenolic hydroxyl groups and a nitrogen atom of azo moiety from the two ligand molecules. AYGG – Cu(II) doped PVA has high dispersion for high frequency lights and vice versa for low frequency lights. Therefore, it is concluded that AYGG – Cu(II) doped PVA film is suggested as a selective filter for ultraviolet and high frequency visible lights for many optical applications like protective shields for solar cells and packaging.
