本研究分兩部份，首先是利用感光材料俗稱甲基紅[2-(4-Dimethylaminophenylazo) benzoic acid]作為偶氮單體，並選用4種不同的材料2-(3-氨基丙基)胺[Bis(3-aminopropyl)amine,簡稱BAA]、三羥甲丙烷三聚丙二醇醚(氨基封端) [Trimethylolpropane tris[poly(propylene glycol), amine terminated] ther,簡稱TPGA]、聚丙烯胺-丙胺枝狀物[Polypropylenimine tetramine dendrimer,簡稱PPI]及聚乙烯亞胺(Polyethylenimine Branched,簡稱 PEI)作為基材，前三者屬於分子量較小的小分子基材，後者屬於分子量較大的高分子基材，探討基材分子量大小對偶氮苯複合材料的光學儲存效率影響。另一方面，利用矽基材3-氨丙基三乙氧基硅烷[3-aminopropyl)triethoxysilane, 簡稱APTES]會溶凝膠反應的特性，控制其溶凝膠反應時間，觀察對材料的光學特性及綠光干涉後表面形貌影響。
利用光功率計測量材料經綠光干涉後的繞射光強度並記錄，數據計算後可得繞射效率。我們可藉由FTIR數據觀察材料鍵結，觀察基材與偶氮苯單體是否鍵結。透過薄膜特性分析儀，觀察材料曝光時亮案區的折射率差異。AFM可以觀察材料表面形貌的變化，得知光柵週期和表面起伏深度。
目前可確認以BAA、TPGA、PPI以及PEI為基材的材料最大繞射效率分別為28.30%、17.80%、25.17%和18.42%，達最大繞射效率時間分別為18分鐘、18分鐘、9分鐘以及30分鐘，可由此得知結果得知基材分子量越大光柵形成越慢，達最大繞射效率時間越長。
使用APTES為基材的複合材料反應時間3~7天最大繞射效率分別為14.07%、11.21%、10.09%、6.00%、5.91%。數據顯示最大繞射效率會隨著溶凝膠時間的增加而下降，其中溶凝膠反應時間為3天擁有最高繞射效率。經由AFM觀察表面起伏光柵的起伏深度，材料AP/MR反應4~7天起伏深度分別為206.52 nm、316.80 nm、359.58 nm、314.60 nm，隨著sol-gel的反應時間增加，表面起伏光柵的起伏深度也跟著上升。

The study has two part, the first is we select four different materials as the matrix. They were Bis(3-aminopropyl)amine (BAA), Trimethylolpropane tris[poly(propylene glycol), amine terminated] ther (TPGA), Polypropylenimine tetramine dendrimer (PPI) and Polyethylenimine Branched (PEI). They were used to combine with azobenzene material 2-(4-Dimethylaminophenylazo) benzoic acid (MR). We discussed effect of matrix on their holographic storage efficiency. On the other hand, we used inorganic matrix APTES to control the sol-gel time by sol-gel process. We can discern the surface profile and optical characteristic influence of hologram materials.
We can use power meter to measure diffraction light intensity and get the diffraction efficiency by calculated. The FTIR indicated the material chemical bonding type and degree of gelation. The difference in refractive index between the materials before and after exposure was observed using a N&K analyzer. By AFM, we known the surface profile of material.
The diffraction efficiency of the composites BAA/MR, TPGA/MR, PPI/MR and PEI/MR were 28.30%, 17.80%, 25.17% and 18.42%, respectively. The first order maximum diffraction efficiency time is 18 minutes, 18 minutes, 9 minutes and 30 minutes, respectively. The result shows larger molecular weight matrix needs more time to form surface relief grating.
The diffraction efficiency of the azobenzene composites which matrix is APTES reacted three to seven days were 14.07%, 11.21%, 10.09%, 6.00%, 5.91%, respectively. We can observe the maximum diffraction efficiency occur when sol-gel time is three days by the data. The AFM indicated modulation depth of the azobenzene composites which matrix is APTES reacted four to seven days were 206.52 nm, 316.80 nm, 359.58 nm, 314.60 nm, respectively. The data shows the reaction time of sol-gel increases, the modulation depth of the surface relief grating increases.
