- Аннотация: In this Letter, we show functionalization of NiO-doped 7.5Li2O · 2.5Na2O · 20Ga2O2 · 35SiO2 · 35GeO2 glass by space-selective nanocrystallization via exposure to the focused beam of a pulsed copper vapor laser (510.6 and 578.2 nm) at temperature close to the glass transition point (570°C). Irradiated areas drastically change their color, caused by electronic transitions of Ni2+ dopant ions, without any alteration of the optical quality. Importantly, irradiated regions acquire broadband infrared luminescence (centered at about 1400 nm and possessing 400 nm effective bandwidth) typical of Ni2+ ions in crystalline environment, and by positive change of refractive index (more than 10-3). Spectroscopic and diffractometric data of the irradiated regions indeed resemble those previously observed in thermally nanocrystallized glass, with Ni2+ ions embedded in γ-Ga2O3 nanocrystals. The results demonstrate the possibility of laser writing nanocrystallized multifunction patterns in germanosilicate glasses for the fabrication of active integrated devices. © 2013 Optical Society of America.
