In this research, zinc, calcium and cadmium organometallic nanostructures were synthesized as fluorescent materials for the application in organic light-emitting diodes (OLEDs). High luminescent ZnQ2, CaQ2, And CdQ2 organometallic nanostructures were synthesized by the simple precipitation method using 8- hydroxyquinoline ligand (8-hydroxyquinoline), cationic surfactant of trimethyl ammonium bromide (CTAB) and zinc, cadmium and cadmium salts. The crystalline and amorphous nature of ZnQ2, CdQ2 and CaQ2 organic-metal nanostructures was confirmed by X-ray diffraction (XRD). The synthesized organic-metal complex nanostructures were characterized using Fourier transform infrared (FT-IR) To determine functional groups and scanning electron microscope (SEM). Optical and luminescence properties of the complexes were analyzed by visible and ultraviolet (UV-Vis) and photoluminescence (PL) spectroscopy. The maximum Green-blue emission peaks were observed from ZnQ2, CdQ2, and CaQ2 nanostructures at 498, 488, and 494 nm, respectively. The optical and electronic studies of the samples show that the synthesized nanostructures can be used in liquid crystals displays (LCDs) as well as in light-emitting diodes as an emission and electron transport layers.
