Inquisition of reaction parameters on the growth and optical properties of ZnO nanoparticles synthesized via low temperature reaction route

A Facile Synthesis of Granular ZnO Nanostructures for Dye-Sensitized Solar Cells

“…The high excitation binding energy leads to excitonic transitions (∼25 ∘ C), high radiative recombination efficiency for spontaneous emission, and a low threshold voltage for laser emission. The quantum confinement effect of photogenerated electron-hole pairs and the tunability of optical and electronic properties of ZnO nanoparticles (∼10 nm) [3,4] allowed them to be used in various nanodevices such as information storage, sensing, and surface acoustic wave devices [5][6][7].…”

Morphological evolution of ZnO microspheres from Zn5(OH)8Ac2·2H2O by ultrasonic irradiation method

“…Makkar et al fabricated ZnO nanoparticles via a low temperature reaction route, in which triethanolamine (TEA) was used as a chelating agent and citric acid and polyvinylpyrrolidone (PVP) played important roles. 22 Jiang et al fabricated monodispersed ZnO colloidal microspheres by using a triethanolamine (TEA) aqueous solution as the solvent at low reaction temperatures ranging from 150 to 200 uC. 23 Xu et al reported ZnO nano/ micro-sized ZnO spheres assembled from the aggregation of nano-particles by a one-step method and discussed the relation between the ZnO sphere size and the volume ratio of TEA to H 2 O.…”
