Description

technical field [0001] The invention relates to the field of optical limiting materials. More specifically, it relates to a broadband optical limiting material and its preparation method and application. Background technique [0002] With the rapid development of laser technology, laser has been applied in many fields, and corresponding laser protective materials have been more and more researched and reported. Among them, laser limiting materials based on nonlinear optical effects have attracted widespread attention due to their high-resistance and low-pass effects on lasers. For example, organic conjugated molecules represented by large π-electron conjugated systems such as fullerenes, porphyrins, and phthalocyanines and their derivatives are easy to modify and derivatize their structures, easy to control their properties, and have high nonlinear coefficients. Features such as fast response speed, showing high optical limiting performance. However, such materials have l...
