| 摘 要： | 用旋涂法制备了一种菁染料－聚合物薄膜，并研究了该染料－聚合物薄膜的光谱性质和光存储性能。该染料薄膜在６６０～８３０ｎｍ波段有较强的吸收和２０％以上的反射率。在最佳实验条件下，获得了５８ｄＢ的信噪比。信噪比（ＣＮＲ）、载波信号强度（Ｃ）和薄膜反射率变化（ΔＲ）的对数（ｌｇΔＲ）成正比 |
| 关 键 词： | 菁染料，旋涂法，光存储 |

| Abstract: | A cyanine polymer coating was prepared by spin coating process on pregrooved PC substrate, and its optical storage performance was studied. The reflectance and the absorbance at 830 nm of the coating are high enough for optical storage. With optimum recording condition, 58 dB CNR was obtained. The CNR, C (carrier signal level) have following relations with ΔR (change of relfectance of the coating before and after recording): C∝lgΔR, CNR∝lgΔR. |
| Keywords: | cyanine optical storage spin coating. |
