Synthesis, Characterization and Optical Properties of La-Doped ZnO Nanoparticles Prepared by Precipitation Method

Abstract:

ZnO and La-doped ZnO nanoparticles were synthesized by precipitation method by using Zn (CH₃COO)₂2H₂O, (CH₂)₆N₄, (PEO)₁₂₈-(PPO)₅₄-(PEO)₁₂₈ and LaCl₃H₂O as zinc source, precipitating agent, capping agent and dopant, respectively. The calcined samples exhibited a hexagonal wurtzite structure. The smallest particle size of pure ZnO nanoparticles of about 88 nm was obtained when 0.7 mmol (PEO)₁₂₈-(PPO)₅₄-(PEO)₁₂₈ was used. The particle size of La-doped ZnO nanoparticles increased when La concentrations increased. The La-doped ZnO nanoparticles showed the energy band gap between 3.159-3.222 eV.
