利用高数值孔径的短波长光盘静态测试仪研究了三硝基溴硼亚酞菁(BTN-SubPc)薄膜的静态光存储特性. 结果表明, 该薄膜不仅适于红光(632.8 nm)记录, 用较小功率(8 mW)和脉宽(200 ns)的Ar+激光(514.5 nm)辐照膜片时, 也可获得大于30%的反射率对比度, 显示出该类材料用作短波长(蓝绿光)高密度光存储介质的巨大潜力. 同时, 将光存储染料的应用波段拓展到了吸收带的短波边, 为双波长记录/读出的实现和短波长记录材料的选择提供了一种新的思路.
The static optical storage properties of BTN-SubPc films were investigated by using a short wavelength optical disk static tester with high numerical aperture. The results show that the films are suitable not only for red light recording (632.8 nm) Reflectivity contrast of greater than 30% is also obtained with Ar + laser (514.5 nm) irradiated diaphragms of smaller power (8 mW) and pulse width (200 ns), showing the use of such materials as short wavelength Optical) high-density optical storage media.At the same time, the application of optical storage dyes is extended to the shorter wavelength band of absorption band, which provides a new method for the realization of dual wavelength recording / reading and the selection of short wavelength recording materials Ideas.
