有機敏光劑於照光時可具有強氧化力，實驗結果發現：敏光劑Phenosafranin (PSF)於照光時可氧化電子授予者，N,N-diethyl-2-
methyl-1, 4-phenylenediamine(簡稱DEPD)，被氧化的DEPD可與α-naphthol發生偶合反應而生成藍色產物Indophenol blue。利用此一光誘發電子轉移反應，吾人設計出一無銀式感光呈像系統。本實驗亦利用凝膠法固定敏光劑以製備無銀感光薄膜。實驗顯示此薄膜仍保有光催化生成Indophenol blue的效果。實驗亦發現薄膜的組成、氧氣的存在及外加電壓的施予均會影響感光薄膜的呈像品質

In our experiment, we used organic dyes to replace the Ag+ ion that often serves as the photosensitizer in traditional Ag+-based photographic films. For instance, phenosafranin can oxide N,N-diethyl-2-methyl-1,4-
phenylenediamine (DEPD) during illumination. As DEPD is oxidized, it will react with α-naphthol and form a blue product, indophenol blue.
Based on these photochemical properties, a non-silver-based photographic system was developed. Experiment showed that sol-gel modifications are useful tools to fabricate the dye-containing films and modified electrodes for image recording. Many factors including the sol-gel formulas, oxygen effects and the applied voltage are important for the sensitivity and quality of these sol-gel based films.
