Abstract

The invention discloses a method for controllably precipitating the crystal phase of transparent glass ceramics for ultra-wide-band fiber amplifiers. The base glass comprises fixed components and a variable component, wherein the fixed components comprise 41.9 parts of SiO2, 11.7 parts of Al2O3, 4 parts of ZnO3, 10.7 parts of K2O and 0.01-1.5 parts of transition metal ion oxides; the variable component comprises Li2O with the part greater than or equal to 0 and less than or equal to 10. Through adjusting the content of the variable component LiO2, one or more than one of beta-Zn2SiO4, Zn1.7SiO4, Li1.14Zn1.43SiO4 and Li2ZnSiO4 microcrystals can be precipitated in the base glass. The glass ceramics prepared by adopting the method disclosed by the invention have ultra-wide-band fluorescence luminescent property (1000-1600nm); the emission peak full width at half maximum is 200-400nm; the glass-ceramics can be applied to the ultra-wide-band fiber amplifiers.

Description

technical field [0001] The invention relates to a method for controllable precipitation of crystal phases of transparent glass-ceramics, in particular to a method for controllable precipitation of crystal phases of transparent glass-ceramics for ultra-broadband optical fiber amplifiers. technical background [0002] Glass-ceramic refers to a class of composite materials in which nanocrystals are distributed in a continuous glass phase. The preparation method is usually to first prepare a matrix glass with designed components, and then heat-treat the prepared matrix glass at a certain temperature to precipitate nanocrystals in situ, that is, to obtain a glass-ceramic. Glass-ceramics also has the characteristics of stable physical and chemical properties of glass, high mechanical strength, and easy processing, and has the characteristics of low phonon energy in crystals, which can reduce the non-radiative transition probability of doped luminescent ions and improve its quantum...
