摘    要:利用旋涂法,制备了以二乙基胺基〖N(CH2CH3)2〗作为推电子基因、以具有强电负性的羧基(COOH)作为拉电子基团的推-拉型偶氮染料掺杂的高分子(PMMA)薄膜。在室温下测试了该偶氮染料在溶液和薄膜态的吸收光谱、薄膜态的反射光谱和透过光,发现该薄膜在400~550nm波长范围内具有强的吸收。在514.5nm光盘静脉测试仪上测试了膜片的静脉光存储性能,结果表明,用低功率Ar^+激光(514.5n

Abstract:A novel push pull azo dye doped polymer film has been developed for write once optical recording. The absorption spectra of the spin coated thin films show a strong and broad absorption region at 400~550 nm, which matches well with the wavelength of Ar + laser. The optical recording performance of the azo dye doped polymer thin films shows that higher reflectivity contrast can be obtained at lower writing power and writing pulse width using the Ar -+ laser (514.5 nm) irradiation. These results demonstrate that the single layer of azo dye doped PMMA thin film is a promising candidate for short wavelength optical recording.
Keywords:optical recording material    azo dye film    polymer
