摘要：
A photochromic material can include nanoparticles of lanthanide-activated strontium aluminate (NLSA) embedded into polyethylene terephthalate (PET). The PET may further include electrospun polypropylene nanofibers (PPNF) incorporated therein. In some embodiments, the photochromic material may be transparent. In other embodiments, the photochromic material may be scratch resistant. In some embodiments, the photochromic material may be configured to form concrete. In still other embodiments, the photochromic material may be configured to form windows. The electrospun polypropylene nanofibers may be a roughening agent in the PET. The photochromic material may exhibit a green coloration after exposure to ultraviolet (UV) light. The NLSA may have a diameter of about 80 nm to about 120 nm. The PPNF may have a diameter of about 75 nm to about 180 nm. The photochromic material may be superhydrophobic.
