利用旋涂法 (spin coating)制备了一种新的菁染料薄膜 ,并进一步制备成可录型数字多用光盘 (DVD R) ,测试该菁染料溶液和薄膜的吸收光谱 ,薄膜的透过、反射光谱 ,用椭圆偏振光谱仪测试了薄膜光学常数n和k ,发现薄膜在 6 30～ 6 5 0nm波段内有良好的吸收和反射特性。在 6 32 8nm光盘动、静态测试装置和 6 5 0nm光盘性能测试仪上测试了以该染料薄膜为记录层介质的DVD R光盘 ,结果表明盘片具有良好的光存储性能。 A new cyanine dye thin film was prepared by spin coating and further prepared into a recordable digital versatile disk (DVD R). The absorption spectra of the cyanine dye solution and the film, the transmission and reflection of the film Spectra. The optical constants n and k of the films were measured by ellipsometer. The results show that the films have good absorption and reflection properties in the band of 6 30 ~ 650 nm. The DVD R disc with the dye film as the recording layer medium was tested on a 632 8nm optical disc dynamic and static testing device and a 650nm optical disc performance tester. The results show that the optical disc has good optical storage performance.
