Abstract
A photochromic material can include nanoparticles of rare-earth activated strontium aluminate (NRESA) embedded into polylactic acid (PLA). 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 an anti-counterfeiting substance. The photochromic material may exhibit a green coloration after exposure to ultraviolet (UV) light. The NRESA may have a diameter of about 10 nm to about 15 nm. The electrospun photoluminescent nanofibrous film may have a fiber diameter of about 50 nm to about 200 nm.
