In the preparation method of the invention, cellular glass distributed with nanoscale micropores is adopted, and the iron nano particles are prepared in the micropores; and the process is simple, the preparation period is short, and the iron nano particles of the obtained cellular glass containing iron nano particles are evenly distributed.

Description

technical field [0001] The invention relates to the field of glass preparation, in particular to a porous glass containing iron nanoparticles and a preparation method thereof. Background technique [0002] The composite material obtained by doping metal particles is a functional material that plays an important role in the fields of optics, electronics, antibacterial and catalysis. As early as the 4th century AD, Roman glass workers knew how to dope glass with gold, silver and other metal particles to prepare glass products with rich and beautiful colors. Nowadays, with the development of nonlinear optics, especially since American scientists Jian and Lind studied the third-order nonlinear properties of glass doped with nanoparticles in 1983, people's research on glass doped with metal particles has begun to focus on its optical properties. aspect. When metal nanoparticles are incorporated into glass, the glass matrix isolates the particles from each other, forming quantum...
