Abstract We study the absorption and transmission spectra, the thermal stability and the green-light (514.5 nm) static optical recording properties of nickel phthalocyanine (NiPc) thin film. It is found that this film occupies suitable absorption and transmission properties, excellent thermal stability (decomposition point > 600°C) and outstanding thermal decomposition characteristics (weight loss in one step decomposition > 60%) for green-light (514.5 nm) optical recording. High reflectivity contrast (> 50%) was obtained at low writing power (5 mW) and short writing pulsewidth (100 ns) using an Ar+ laser (514.5 nm) irradiation. Compared with azo in polymer films, the subphthalocyanine film and Sb-Te-Based phase change films, the NiPc film has better green-light static recording properties. These results indicate that metal phthalocyanine is not only a qualified material for near infrared optical recording but also a promising recording medium candidate for green-light DVD-R.
