Optical properties and recording characteristics of phthalocyanine-derivative LB films
暂无分享,去创建一个
Langmuir-Blodgett (LB) films of tetra-neopentoxy phthalocyanine zinc and tetra-nonyl phthalocyanine copper are prepared. Their structures, optical properties, and temperature dependencies are investigated. Static optical recording tests by He-Ne laser are done in these LB films and the experimental results demonstrate that phthalocyanine derivates are useful for phase change type erasable data storage media.
