Preparation of indium-doped zinc oxide nanoparticles by pulsed laser ablation in liquid technique and their characterization

Abstract

Indium-doped zinc oxide (IZO) nanoparticles (NPs) are produced by pulsed laser ablation in liquid technique. The influence of indium doping on the sizing, structure, morphology and optical properties of nanoparticles was investigated using X-ray diffraction (XRD), transmission electron microscope (TEM), energy dispersive spectrum, UV-Visible and photoluminescence spectroscopies. The XRD results demonstrated that indiumdoped ZnO maintained a hexagonal wurtzite structure with a (002) preferential orientation. With reference to the TEM images, the particle size increased with an increase in the doping ratio, and the morphology varied from particle to aggregated spheres and then to NPs. The optical absorption spectra increased with an increase in In-doped concentration, while the band gap had reduced. In addition, the photoluminescence spectrum had a broad green emission from IZO nanoparticles.

Impact of composition on microstructural, electrical and optical properties of ZnO thin films incorporation by In 2 O 3 for solar cells

“…This decrease in the strain coupled with increased crystallite size (from 2 to 6 of In 2 O 3 doping) indicate that the decrease in the density of lattice imperfections resulting from addition of In at expense of Zn in the films. After 2% In dopant, the incorporation of indium ions at the zinc ion sites increases, which results in that some dopant atoms do not replace the lattice sites, but become interstitial atoms, thereby structurally generates additional stress, which reduces peak broadening to 6% and improves crystallinity and grain growth due to coalescence 14,20 . Furthermore, the incorporation of larger In 3+ ions in place of host sites produces additional train staining to increase crystal size 15,21 .…”

“…9,10 In recent years, the ZnO/In 2 O 3 system has attracted much attention due to its good electro-optical properties and high chemical stability. Thin films of indium-doped zinc oxide can be fabricated using spray pyrolysis, 11 chemical vapor deposition, 12 electron beam evaporation, 13 pulsed laser deposition, 14 and sputtering. 15 Most of these techniques require complex instrumentation and/or high deposition temperatures.…”

Plasma Synthesis of Advanced Metal Oxide Nanoparticles and Their Applications as Transparent Conducting Oxide Thin Films

“…The XRD diffraction peaks showed good crystallinity and no In 2 O 3 or other indium suboxide phases were observed in IZO1. However, in IZO2 sample, the In 2 O 3 phase was observed along with main wurtzite peaks indicating that at the higher doping amount of 8 atm % indium, excess In 3+ cannot substitute for Zn sites and was precipitated as indium oxide phases [ 94 ].…”

“…10, pp: 2590-2598 2591 different types of nanomaterials with various shapes of nanoparticles. Furthermore, it can be used to reduce the size of initial particles in liquid, by reshaping and de-agglomerating the nanoparticles [2][3][4][5][6][7][8][9][10]. In general, nanosize structure materials have a great importance in recent years because of their good properties and their perfect applications in different fields [11][12][13][14][15][16][17].…”
