Abstract

The invention relates to a solid naphthalocyanine device with excellent optical limiting properties. The device is made by the following steps: adding tetraethoxysilane, diglycidyl ether propyltrimethoxy siloxane, analytically pure ethanol and acidic aqueous solution to a reactor; stirring in an enclosed reactor for 2-3h, then opening the reactor and continuing stirring for 1-2h; adding a naphthalocyanine solution and stirring to cause the mixture to become viscous; transferring the viscous mixture to a mould, and taking out after drying to obtain the novel solid naphthalocyanine device with optical limiting properties. The device is made by an organosilicon modification method combined with doped inorganic salt, and by doping naphthalocyanine with a larger pi electron conjugated system to form a continuous random network system with bonded chemical bonds of organic components and inorganic components instead of physical hybrid. The device has good laser resistance and excellent optical limiting properties.

Description

technical field [0001] The invention belongs to the technical field of preparing solid devices by a sol-gel method, in particular to a naphthalocyanine with a larger π-electron conjugated system prepared by combining an organic silicon modification method and doping inorganic salts. Solid Naphthalocyanine Devices with Optical Limiting Properties. technical background [0002] As an important means of modern high-tech warfare, laser technology has been widely used in the military field. Among all kinds of laser weapons, laser jamming and blinding weapons have been researched and applied all over the world in the 1980s. The target of such weapons is the human eye and some important electronic communication equipment and devices. With the development of such weapons, the research on corresponding laser protective materials and devices has attracted great attention. Among them, optical limiting material is one of the important materials for laser protection, and its research ...
