The physical properties of these complexes in different solvents, mainly DMF and DMSO, were studied. Most complexes showed lower absorbance as well as lower refractive index when compared to those of 8-hydroxyquinoline in DMF or DMSO. Some samples showed comparable values due to the formation of nanoparticles within the prepared structures. As well, the zinc-hydroxyquinoline (Znq2) complex showed that two absorption edges with comparable intensities are formed. These results may encourage to consider these complexes for some spectroscopic applications such as laser dyes and random gain media.
