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.

Abstract

An information storage material includes base board and metal organic complex film set on the base board which is made of glass or some other material with good transparency. The applied metal refers to any one of K, Na, Cu and Ag. The material has excellent practical applicability as having many times of circulation for writing and erasing which can be done in short time.

Description

technical field [0001] This invention relates to materials, and more particularly to materials for information storage. Background technique [0002] In recent years, due to the high information storage density of optical discs, they are more and more popular among people. However, the existing magneto-optical discs of commercial products need to add light and magnetic field at the same time when "writing" and "erasing", so the equipment is more complicated. And other types of optical discs have not yet reached the commodity level. At present, photochromic optical discs have become a development direction because they can perform multiple recordings at the same point with light of different wavelengths. However, the photochromic optical discs of the existing materials have few cycle times and long writing and erasing time, which are not suitable for people's needs.
