The optical properties of mixed donor ligand directed semiconductor ZnO nanoparticles are evaluated and imine linked receptor is used as capping agents. The ZnO nanoparticles are prepared using precipitation method. The ligand is synthesized using condensation reaction between 2-aminothiophenol and 2-thiophenecarboxaldehyde. The formation of ligand is confirmed with spectroscopic methods including NMR and mass spectroscopy. However, UV–Vis absorption, photoluminescence, X-ray diffraction, energy dispersive X-ray and FTIR spectroscopy techniques are used for characterization of the ligand coated ZnO nanoparticles. The capping with ligand resulted in the successful amendment of the surface of ZnO nanoparticles, as it particularly reduced the defects related visible emission known as green luminescence and hence resulted in improvement in the UV luminescence. The UV–Vis absorption spectra also showed blue shift in the UV region for the ligand based ZnO nanoparticles due to the effect of quantum confinement. The composite (ZnO-ligands) stability is confirmed theoretically with Density Functional Theory.
