中文摘要	a novel metallized azo dye has been synthesized. the absorption spectra of the thin film and thermal characteristic are measured. static optical recording properties with and without the bi mask layer super-resolution near-field structure (super-rens) of the metal-azo dye are investigated. the results show that the metal-azo dye film has a broad absorbance band in the region of 450-650 nm and the maximum absorbance wavelength is located at 603 nm. it is also found that the new metallized azo dye occupies excellent thermal stability, initiatory decomposition temperature is at 270 degrees c and the mass loss is about 48% in a narrow temperature region (15 degrees c). the complex refractive index n (n = n + ik) is measured. high refractive index (n = 2.45) and low extinction coefficient (k = 0.2) at the recording wavelength 650nm are attained. static optical recording tests with and without super-rens are carried out using a 650nm semiconductor diode laser with recording power of 7mw and laser pulse duration of 200ns. the afm images show that the diameter of recording mark on the dye film with the bi mask layer is reduced about 42%, compared to that of recorded mark on the dye film without super-rens. it is indicated that bi can well performed as a mask layer of the dye recording layer and the metallized azo dye can be a promising candidate for recording media with the super-resolution near-field structure.
