中文摘要	zno nanoparticles were synthesized in ethanolic solution using a sol-gel method. the structural and optical properties were investigated by x-ray diffraction, transmission electron microscopy, uv absorption, and photoluminescence. after annealing at 200 degrees c, the particle size is increased and the peak of defect luminescence in the visible region is changed. a yellow emission was observed in the as-prepared sample and a green emission in the annealed sample. the change of the visible emission is related to oxygen defects. annealing in the absence of oxygen would increase oxygen vacancies.
