Short-wavelength static optical recording properties of subphthalocyanine thin films 总被引:2,自引:0,他引:2
The static optical recording properties of novel bromoboron trinitro-subphthalocyanine (BTN-SubPc) thin films were studied
using a self-developed short-wavelength optical disk tester with high NA objective lens. High reflectivity contrast (>30%)
was obtained at low writing power (8 mW) and short writing pulsewidth (200 ns) using the Ar+ laser (514.5 nm) irradiation. These results demonstrate that subphthalocyanine is not only qualified for red-light recording
but also a promising candidate for the recording medium of a green-light DVD-R. The leading edge, just like the falling edge,
of the dye’s absorption band can also be used to realize optical disk storage if an appropriate reflector was used. It provides
a new clew for double-wavelength writing/reading and choosing short-wavelength recording materials. 相似文献
