Research of Organic-Inorganic Hybrid Method for the Optical Storage Properties of Holographic Data Storage Material
摘要
全像儲存技術由於具有高儲存容量(High Density Data Storage)及高傳輸速率(High Transfer Rate)的優點，將成為最有希望的新世代光資訊儲存技術。而此技術最重要之關鍵為開發具有良好的基材尺寸穩定性與光致折射效應之記錄材料。本研究內容為製備具有低收縮率之藍光雷射全像光儲存材料，以溶膠-凝膠法(Sol-Gel method)合成TSPEG/TEOS有機-無機混成基材，以DAPP為高分子單體(Monomer)與PQ為光起始劑(Photoinitiator)，藉由藍光407nm之雷射光源照射之干涉光的強弱使高分子單體產生不同程度的聚合反應造成折射率的差異性，達到記錄資訊之目的。並以多種量測實驗探討所製備材料其特性，包括紫外線/可見光分光光譜儀、傅立葉轉換紅外線光譜儀、熱差式掃瞄卡計儀、熱重分析儀、掃描式電子顯微鏡、原子力顯微鏡等儀器。 實驗結果發現此記錄材料在藍光波段(407nm)具有吸收性，可有效的進行記錄且具有良好之機械性質；進行全像記錄後，繞射效率可達66%，其材料記錄區域之收縮率僅有0.145%。

Holographic data storage is the most promising data storage technology in the next generation due to the advantages of the high data storage density and high data transfer rate. A good dimensional stability of matrix and photorefraction effect of the grating are the two most important factors for holographic storage. In this study, a blue laser holographic material with low shrinkage was prepared. The organic-inorganic hybrid matrix is triethoxysilylpropyl polyethyleneglycol carbamate (TSPEG) homogeneously bonded with tetraethyl orthosilicate (TEOS) prepared by sol-gel method. Diallyl phthalate pre-polymer (DAPP) and 9,10-Phenanthrenequinone (PQ) were used as a monomer and a photoinitiator, respectively. Data recording was by 407 nm laser source. The photoinduced polymerization of DAPP by PQ was demonstrated. The effect of matrix composition was investigated by UV-vis, FTIR, DSC, TGA, SEM and AFM. The result shows that blue laser holographic material with high diffraction efficiency of 66% was prepared in this study. DAPP monomer and PQ photoinitiator is able to record data by 407nm blue laser. The shrinkage measurement showed that the blue laser holographic material with TSPEG/TEOS=0.2 has shrinkage as low as 0.145%.
