碩士 === 國立臺北科技大學 === 光電工程系研究所 === 95 === This research investigated the growth of ZnO nanostructures at 350oC~700 oC by ultrasonic-spray-assisted VLS mechanism. First of all, put the gold-contained solution into the Ultrasonic Spray system . With the high frequency vibration action of Piezoelectric crystals, gold-contained solution will create the foggy phenomenon. Meanwhile get it through with carrier gas (O2) so that to drop the produced foggy liquid on the silicon; in addition, use this as the resource of gold nanoparticles. Not long later, put ZnO powders on the center of the tube furnace and put deposited the silicon substrates at the right spot, then vacuum the system. After that, control the needed the cusec and the growth pressure of the carrier gas. We are about to work the tube furnace. After the reaction is done, we can get the construction of the ZnO nanorod. By changing the time, the substrate temperature, the ambient pressures, the gas flow rate and the diameters of gold nanoparticles, their influences on the ZnO nanostructures were investigated. The characteristics of ZnO nanostructures were analyzed by scanning electron microscope and photoluminescence spectra and X-ray diffraction to observe their average diameter, morphology and crystallization.
