Synthesis and Characterization of ZnO Nanoparticles and Alq3 for Fabrication of Alq3/ZnO Nanocomposites| Chapter 10 | Recent Trends in Chemical and Material Sciences Vol.6

The fluorescent matrix of Tris-(8-Hydroxyquinoline) Aluminium and the optical and electrical properties of semiconducting Zinc Oxide (ZnO) nanoparticle systems were investigated (Alq3). To better understand these features, we used an aqueous sol-gel approach to make ZnO nanoparticles with particle sizes ranging from 23 nm to 110 nm, annealed them at high temperatures, and made an Alq3 compound of planar shaped microparticles. At room temperature, we evaluated the dielectric characteristics of Alq3/ZnO nanocomposites made by mixing and grinding in a specified volume fraction ratio. To evaluate the optical and chemical properties of ZnO and Alq3 components, measurement techniques such as X-Ray Diffraction (XRD), Ultraviolet (UV) Spectroscopy, and Fourier Transformation Infrared (FTIR) spectroscopy were used. In addition, structural characteristics, particle morphology, and elemental phase analysis of ZnO nanoparticles and Alq3 powder are studied using Field Effect Scanning Electron Microscopy (FESEM) and Energy Dispersive X-Ray Spectroscopy (EDS/XDS). An impedance analyzer with a frequency range of 20 Hz to 25 kHz was used to estimate the dielectric constant of various mixes of Alq3 and ZnO in Alq3/ZnO nanocomposite systems. In general, the purpose of this article is to describe the synthesis, fabrication processes, and characterisation of composite materials made of ZnO and Alq3. We also discuss some interesting organic electronics applications, such as organic light-emitting diodes (OLEDs), organic photovoltaic cells (OPVC), and so on.
