Embodiment 1
[0015] Use glass as the substrate, take the metal as Ag, and δ is 0.6, generate Ag layers and tetracyano-para-acetal dimethane layers alternately, and make it undergo solid-state reaction through heat treatment to generate Ag and organic tetracyano-para-acetal groups Dimethane complex thin film, the thickness of which is 200 nanometers, and then plated with Al layer, can make optical disc material. The number of cycles of the laser read-write-erase test is more than 1200 times, the writing time is 200 nanoseconds, and the erasing time is about 10 microseconds.
Embodiment 2
[0017] Use glass as the substrate, take the metal as Cu, and δ is 0.5, generate Cu layers and tetracyano-p-aldehyde dimethane layers alternately, and make it undergo solid-state reaction through heat treatment to generate Cu and organic tetracyano-p-aldehyde groups Dimethane complex thin film, the thickness of which is 200 nanometers, and then plated with Al layer, can make optical disc material. The number of cycles of the laser read-write-erase test is more than 1000 times, the writing time is 220 nanoseconds, and the erasing time is about 10 microseconds.
Embodiment 3
[0019] Quartz is used as the substrate, the metal is K, and δ is 0.3, and the K layer and the tetracyano-para-acetal dimethane layer are alternately formed, and a solid-state reaction occurs through heat treatment to generate K and the organic tetracyano-para-acetal group Dimethane complex thin film, the thickness of which is 200 nanometers, and then plated with Al layer, can make optical disc material. The number of cycles of the laser read-write-erase test is more than 1500 times, and the writing time is 200 nanoseconds. The erase time is around 10 microseconds.
