Laser Microinscription

Laser Microinscription

Photochromic silver-containing mesoporous titania thin films are used as writable or rewritable data carriers. Continuous wave UV and visible laser radiations, respectively, can either repeatedly print and completely erase micropatterns on their surface or engrave permanent micropatterns, depending on the laser intensity.
