| Summary: | 碩士 === 淡江大學 === 機械與機電工程學系碩士班 === 98 === This research has brought a new method to fabricating silver chloride films. The silver nitrate solution phase-changed into solid phase and the sodium chloride solution were infused, and then the silver chloride film was produced by precipitation reaction. And the research is a study of the effects on the crystalline morphology of AgCl film which grew in the UV-exposed environment and in the darkness, respectively. The crystalline morphology of AgCl film upper-surface which grew in the darkness is close to equiaxed crystals. The crystalline morphology of AgCl film under-surface is small particles which heterogeneously nucleated on the nitrate crystals under the surface of the film and to be in accordance with the preferred orientation into the stick-like structure. As the crystalline AgCl film grew in the UV-exposed environment, the AgCl crystal became a long axis crystal due to the silver clusters as heterogeneous nucleation site. And the crystal is identified with a higher aspect ratio. The silver clusters were derived from AgCl crystal photodecomposition which was caused by UV rays irradiation.
