英文摘要	a nickel(ii)-azo dye was synthesized in order to obtain a suitable optical recording medium for write-once blu-ray recording with low-to-high signal polarity. smooth thin film of the nickel(ii)-azo dye was prepared by spin-coating method. absorption, reflectance spectra and optical constants (complex refractive indices n=n+ik) of the thin film were investigated in the wavelength region of 300-700 nm. to demonstrate the physical basis of low-to-high polarity, the relationships between the absorption, reflectivity and optical constants for the nickel(ii)-azo dye in spin-coated films were discussed. it is found that the thin film has a strong absorption band in the wavelength region of 370-500 nm and a strong absorbance at 405 nm. the reflectance spectra show that a low reflectivity of the unrecorded thin film at 405 nm can be obtained. the thin film of the nickel(ii)-azo dye gives a relatively low n value of 1.36 and a relatively high k value of 0.51 at 405 nm. in addition, in order to examine its possible use as a blu-ray recording medium, the spin-coated film of the nickel(ii)-azo dye was studied by a static optical recording testing system. the results demonstrate that high reflectivity contrast (85%) with low-to-high polarity can be obtained at an optimum laser writing power and pulse width using the nickel(ii)-azo dye thin film as the recording layer. moreover, the recording marks on the film are clear, circular, regular, and their size is as small as 200 nm or even less. these results indicate that the nickel(ii)-azo dye is promising for applications in high-performance write-once blu-ray recording systems at 405 nm.
