    Abstract: 本論文之創見在於使用溶膠凝膠法( sol-gel )先將金屬鹽或金屬化合物製成離子態的先導體溶液,混入適當的溶劑,然後再點火燃燒混合液面,可以大量地分析出高品質的奈米粒子粉體。 這是一種非真空物理蒸鍍的方法,將被鍍物置於混合溶液共燒液面之火焰上方,加上電場與被鍍物,就可以在非真空環境進行物理蒸鍍。 亦可以使用電場將上述點火共燒所生成的奈米粒子變成帶電荷粒子,當這些帶電荷粒子於空間行進,再與磁場向量旋積(curl),使這些帶電荷粒子行進途徑發生旋轉,就可以使不同分子量的奈米粒子生成物依質量差異被分離出來。此時可選擇適當的位置蒐集所生成的奈米材料,或將被鍍物放至於所需的位置;就可以將所選擇的奈米鍍物材料電鍍於被鍍物表面。 本法所生成的奈米粒子粉體因生成速率快、粉體粒徑小、晶格配位佳且係於高溫條件中生成(高溫粉體),所以可以在自然常態(非真空狀態)進行物理蒸鍍與電鍍。故本方法是一極低污染、高品質和低成本的奈米粒子粉體的製造方法。再配合電磁場的物理特性,可以非常精確地操控與分離所生成的奈米粒子,並進行物理電鍍(PVD)製程,如此就建構成一完整的「奈米平台」。 (本論文已於西元2000年開始申請台灣、中國、美國、歐盟與日本等國之專利,並已於中國、日本等國公告) The project is to develop an economic nanotechnology platform for both synthesis and manipulation of inorganic nanoparticles. Sol-gel process is implemented to produce the precursor solution, and proper organic solvent is mixed into the precursor solution. Ignite the well-mixed solution to synthesize high quality nanoparticles through the co-firing process. As the inorganic compound is ionized by the chemical approach, substances can be completely dissolved, mixed and compounded by agitating the solution for a period of time; thus the component structure of the molecule is consistent. A non-vacuum physical vapor deposition (PVD) process is also performed incorporating devices of electric field and electromagnetic field. As the nanoparticles are electrically charged by electric field, the traveling path of nanoparticles are deflected by the electromagnetic field and driven to the specific objects under control. Nanoparticles of disparate substances spin in arcs of different radii in the electromagnetic field and deposit on designated areas; thus substances can be separated, and the nanoparticles of the desired material can be deposited onto the surface of designated object. This technology platform consists of the flame synthesis process along with manipulation by electric field and electromagnetic field, and the features of this scale-up platform include (a) high yield; (b) high quality; (c) low cost; (d) low pollution; (e) precise manipulation and (f) physical vapor deposition (PVD).
