This paper mainly discusses the performance specification of plasma source ( gis ) , technology and quality of tio2 and sio2 coatings and the technology for large antireflection coatings deposited with plasma - iad . the research shows that the index of optical coating increases remarkably by using plasma ion assisted deposition and approach to the massive material further , the coating structure is more compacted than the one obtained through conventional deposition method and the adhesive power is high as well 研究了用于輔助鍍膜的等離子體源( gis )的結(jié)構(gòu)原理及性能指標(biāo),并從光學(xué)特性、顯微特性和機(jī)械特性三方面著手,研究了使用等離子體源所做的單層tio _ 2膜和單層sio _ 2膜的成膜工藝與質(zhì)量。
An attempt is made to use the filled function as the modified function approach to apply global optimization to optical thin film problems . it is proved successful when applied to problems such as antireflection coatings and beam spliters . meanwhile , it is also found that when the number of layers is fixed those local minima with less total optical thickness appear to be better . in the realization . needle method are made to explore the impact of local optimization methods used , parameter of these methods , the starting design , the search accuracy of function and the methods of thickness growth 從理論分析來看,由于光學(xué)薄膜的特性是由在入射介質(zhì)那一側(cè)的等效導(dǎo)納所確定的, needle方法把等效導(dǎo)納作為狀態(tài)變量,把每一層的折射率作為控制變量,運用最優(yōu)控制的原理計算出在薄膜內(nèi)部每一個厚度對應(yīng)的點上折射率改變所引起的評價函數(shù)的改變,由此選取改變折射率后評價函數(shù)變化最大(評價函數(shù)變小)的那一點進(jìn)行插入。
The resulted films were densely packed uniform amorphous films with substantial overlap between adjacent si02 layers , and can serve the function as antireflection coatings . colloidal ti02 particles of 3 ~ 4nm in diameter were prepared using tetra - h - butyl titauate as precursor , and composite multilayer films of pss / tio2 were electrostatically self - assembled 二氧化硅膠體與聚合物pdda的自組裝多層復(fù)合薄膜為均勻、致密的非晶態(tài)膜,復(fù)合薄膜內(nèi)存在層間穿插的現(xiàn)象,薄膜表現(xiàn)出均質(zhì)單層光學(xué)涂層的特性并具有增透作用。
