本研究以SnCl2·2H2O為前驅物，藉由微波輔助水熱技術，合成出高純度、結晶性佳的SnO奈米顆粒。有別於其他文獻，本研究還從控制溶液pH值、微波加熱溫度以及微波加熱時間等方面出發，提高了SnO的結晶性及純度，且所合成出的SnO其粒徑可以維持在40奈米以下，但由於所合成出的SnO顆粒聚集性嚴重，分散性差，所以，本研究另外還藉由化學方式(異質成核、改變反應物濃度)以及物理方式(改變基板狀態、聚集時間)來對SnO顆粒沉積於基板上的分散性進行改善。而除了合成出小尺寸，分散性佳的SnO，本研究還進一步將所合成出的SnO成功應用在成長TiO2奈米線上。而因為TiO2奈米線不論是在染料敏化太陽能電池或是光觸媒等元件上皆具有相當重要的應用發展，所以也增加了本研究所合成出的SnO其未來應用發展性。最後，本研究利用掃描式電子顯微鏡(SEM)來觀察SnO奈米顆粒之外觀形貌。而在SnO微結構方面則是藉由穿透式電子顯微鏡(TEM)、薄膜X光繞射分析儀(TFXRD)來對其進行結構分析，至於化學成分方面則是使用X光電子能譜儀(XPS)加以測定。

SnO nanoparticles with high purity and good crystalline were just synthesized by using SnCl2．2H2O as a precursor and by means of microwavw-assisted hydrothermal technique in this research。 Different from other literatures，our research just increased crystalline and purity of SnO in terms of controlling pH value of solution、temperature and time of microwave heating，and the particle size of SnO could be retained under 40 nm，but because the aggregation of SnO was just serious，so the dispersion of SnO depositing on ITO-glass also improved by means of chemical and physical methods in this research。 In addition to synthesizing small particle size and good dispersion of SnO，we also growed up TiO2 nanowires successfully by SnO which we synthesized in this research。And because TiO2 nanowires had very important application no matter was on dye- sensitized solar cells or photocatalysis，so the potential of SnO which we synthesized was just increasing。 The morphologies of SnO nanoparticles were analyzed by scanning electron microscope (SEM)。And the microstructures were investigated by transmission electron microscopy (TEM) and X-Ray Thin-Film Diffractometer。 II
Final，the chemical compositions were examined using X-ray photoelectron spectroscopy (XPS)。
