溴化银纳米线的原位显影研究

Probing the Development Process of AgBr in AAO Template

在AAO(Anodic Aluminum Oxide)模板中生长AgBr纳米线,并对其进行原位化学显影。显影结果表明,原位显影得到的银则在孔隙中呈线状分布。文章认为,显影液中物质传质过程及显影剂活性的不同造成了显影银存在位置和形貌的差异,并提出用直接电子转移和间接电子转移机理解释银的形貌差异。

AgBr was deposited in an anodic aluminum oxide （AAO） template, and the photographic development was employed subsequently. It was observed that twined silver wires were formed inside the AAO pores by a developer in situ. It may be resulted from the difference in matter transfer and developer activity. The mechanism of direct electron transfer and indirect electron transfer was applied to explain the differenee of morphology.
