摘　　要：研究了有机染料酞菁铜（ＣｕＰｃ）真空蒸镀薄膜在可见及近红外区域的吸收光谱和光学常数，发现酞菁铜薄膜在５５０～７５０ｎｍ波长范围内具有较强的吸收．在静态测试仪上测试了酞菁铜薄膜的光存储记录特性，发现用低功率氦氖激光辐照样品时薄膜反射率变化较大．在酞菁记录层上覆盖金属反射层将提高写入激光的阈值能量并且增大反射率的对比度．Optical absorption spectra and optical constants of the vacuum sublimed films of copper phthalocyanine (CuPc) .were studied. A comparatively strong absorption was oberved at wavelength region of 550￣ 750 nm. The static optical recording test of a CuPc film indicated that low power He-Ne laser irradiation could produce a relatively large reflectivity change. The introduction of metallic reflective layer on the recording layer will raise the writing threshold energies and maximize the reflectivity contrast.
