Synthesis and characterization of Znq2 and Znq2:CTAB particles for optical applications

Abstract

High luminescent zinc (ii)-bis (8-hydroxyquinoline) Znq2 nanoparticles were synthesized by the simple precipitation method in pure form and with cetyltrimethyl ammonium bromide (CTAB) as cationic surfactant. The crystalline nature of title samples was confirmed by powder X-ray diffraction. Thermo gravimetric analysis and differential thermal analysis were carried out to find the thermal stability of the synthesized samples. The morphology and elemental analyses of the samples were studied by scanning electron microscope and energy dispersive X-ray analyser, respectively. The functional groups of these nanoparticles were analysed and assigned using the Fourier transform infrared spectroscopy spectral study. The optical property of Znq2 and Znq2:CTAB was confirmed by UV-vis-NIR spectral study. The band gap of Znq2 was calculated. The synthesized Znq2 and Znq2:CTAB nanoparticles were confirmed by photoluminescence studies for organic-light-emitting diode applications as emission and electron transport layers.
