碩士 === 逢甲大學 === 光電研究所 === 98 === Zinc Oxide (ZnO) nanospheres were synthesized by sol–gel method. The size of ZnO nanoparticles can be well controlled at the range 100 nm~1500 nm. The growth mechanism and characterization of ZnO nanosphere was investigated. The characterization shows that the morphology of ZnO nanospheres are spherical and the nanospheres consist of many nanoentities with the size of 10nm~20nm. Besides, a close-packed monolayer ZnO structure was demonstrated. The average haze ratio of monolayer ZnO structure achieves 80% at the wavelength of 380 nm~800 nm, when 500nm ZnO nanoparticles were used. An excellent light scattering structure for thin-film solar cell and advanced nano optoelectronic device was demonstrated.
