Optical recording behavior of tetra-neopentoxy phthalocyanine zinc Langmuir-Blodgett film

Langmuir-Blodgett films of tetra-neopentoxy phthalocyanine zinc (TNPPcZn) were prepared. Static optical recording behavior was tested in the Langmuir-Blodgett films of TNPPcZn. The reflectivity contrast was more than 100% in a writing and erasing cycle experiment. This is the first time to our knowledge that writing and erasing experimental data have been obtained in TNPPcZn film.
