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.
