摘要: 本文利用光在多层膜介质中的传播模型,计算了可录型光盘(CD-R)中染料媒体的光学特性.表明在适合于CD-R光盘记录的780nm波长处,由于多层膜中光的干涉作用,样品反射率随薄膜的厚度变化发生振荡.振荡的幅度和周期依赖于染料薄膜的复数折射率(n+ik).当记录介质层的复数折射率在2.1+i0.02至2.8+i0.12之间时,能够满足CD-R光盘对染料介质的要求.通过对三种菁染料薄膜的光谱性质分析及光学参数的模拟计算,证实了该方法用于染料薄膜光学特性研究的合理性.并为选择适合于光记录的染料薄膜的厚度范围提供了简便的方法.

Abstract: Optical characteristics of dye media in compact disc-recordable were calculated by using the model of optical propagation in multilayer structure. It was indicated that the reflection oscillated due to the interaction of the light reflected from the interfaces. The magnitude and the duration of the oscillation was dependent on the complex refractive index(n+ik). To be compatible with the CD standard, the complex refractive index of recording layer must range from 2.1+i0.02 to 2.8+i0.12. This method has been successfully applied for analyzing the reflection spectra and the calculation of optical constants of three cyanine dye films. It has been realized that this method is reasonable and convenient. This method can be also used to calculate the range of dye film thickness fitting for optical recording.
