Synthesis and optical characterization of Cu(mq)2 nanoparticles

Abstract OLED is being considered as one of the most budding technology for flat panel displays. The most important part of OLED devices is the electroluminescence layer, for which polymer and small molecular weight metal chelates can be used. In the present work, Bis (2- methyl 8-hydroxyquinalete) (copper) [Cu(mq)2] nanoparticles were synthesized by simple precipitation method using copper acetate and 2-methyl 8-hydroxyquinalete. The crystalline nature of the Cu(mq)2 nanoparticles were characterized by powder X-ray diffraction (PXRD) analysis. The morphology and the presence of elements in the Cu(mq2) nanoparticles was analyst and proved with scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDAX). The thermal stability of the particles was studied using TG-DTG curve. The functional group of the incorporated particles were confirmed by Fourier transform infrared spectroscopy analysis (FTIR). The wavelength, band gap and luminescence properties of the particles were determined from the UV-visible spectroscopy and photoluminescence spectrum.
