Abstract

Organometallic photochromic complexes, which are more stable than those traditional pure organic photochromic compounds, have a wide variety of potential applications in high-density optical storage. In this paper, Ag-TCNQ and Cu-TCNQ thin films were prepared by physical vapor deposition method. The proportion dependence of the spectral and optical properties of Ag-TCNQ thin films were studied and discussed. Multilayer film configuration was designed and prepared for optical memory study and its short-wavelength (514.5 nm) photochromic characteristics were reported. A recommendation of application of Metal TCNQ complexes for high-density and super high density optical storage was proposed as well.
