Abstract:

Transparent Ni2+-doped ZnO-MgO-Al2O3-SiO2 (ZMAS) system glass-ceramics with broadband infrared luminescence were prepared by heat-treatment of parent glass via melt quenching method. According to DTA results, glass transition temperature (Tg) and maximum crystallization temperature (Tc) of the as-prepared samples are 754℃ and 948℃, respectively. Glass-ceramics obtained from two different heat-treatment systems were characterized by X-ray diffraction, and crystallization behaviors and phase transitions were analyzed. The results show that transparent Ni2+-doped spinel-phase glass-ceramics can be obtained by using two-step heat-treatment process. Ultraviolet-visible absorption spectra and luminescence spectra of the prepared glass-ceramics were investigated. The results indicate that tetrahedral and octahedral sites Ni2+ ions coexist in spinel microcrystals of Ni2+-doped ZMAS system glass-ceramics. The broadband infrared luminescence centered at 1324 nm with full width at half maximum (FWHM) of about 490 nm was observed from the samples. Mechanism underlined these phenomena is attributed to the transitions of 3T2g(3F)→3A2g(3F) of octahedral six-folded Ni2+ in the solid solution of spinel structure of Zn/MgAl2O4. These data confirm that the glass-ceramics may have potential applications for photonic devices such as super broadband optical fiber amplifiers.
