Comparative Static Blu-Ray Recording Properties for Three Metal(II) Complexes in Spin-Coated Films
Smooth thin films of three metal(II) complexes were prepared by spin-coating process from 2,2,3,3- tetrafluoro-1-propanol solution and characterized atomic force microscopy (AFM). In order to examine their possible use as blu-ray recording media, the spin-coated films of the metal(II) complexes on K9 glass substrate with a silver reflective layer were evaluated by static optical recording testing system with a 406.7 nm laser. The morphologies of the thin films are smooth and have a root mean square surface roughness (RMS) of 0.34-0.41 nm with in 5 μ × 5 μ area. The results of the static optical recording test demonstrate that high reflectivity contrast (> 54 %) can be obtained at an optimum laser writing power and pulse width with high-to-low polarity, and the recording marks are durable even after 15000 times readout. In addition, the recording marks on the cobalt (II) complex thin film are very clear and circular, and their size can reach 200 nm or less.
