Abstract

The invention relates to glass-ceramic, in particular to glass-ceramic precipitating Zn1.7SiO4 nanocrystalline. The glass-ceramic precipitating the Zn1.7SiO4 nanocrystalline comprises the following components by weight percentages: 35-50 percent of SiO2, 5-15 percent of Al2O3, 25-40 percent of ZnO, 0-5 percent of Li2O, 0-15 percent of K2O, and 0.01-1.5 percent of transitional metal ion, wherein the transitional metal ion is Cr4+, Ni2+, Co2+, Fe3+ or V5+, and the total percentage of the components is 100. The invention has the advantage that the glass-ceramic precipitating the Zn1.7SiO4 nanocrystalline also has 1,000-1,600 nm ultra-wideband fluorescence performance, is low in requirement on melting temperature of a glass substrate, has a wide heat treatment temperature range greater than 200 DEG C, and facilitates manufacturing production of nanocrystalline products.

Description

technical field [0001] The invention relates to a glass-ceramic, in particular to the preparation of a glass-ceramic doped with transition metal ions, and belongs to the technical field of material science. technical background [0002] The erbium-doped fiber amplifier (EDFA), which was successfully developed in the 1980s, abandoned the traditional photoelectric data transmission mode and directly amplified the optical signal, effectively overcoming the electronic bottleneck problem of the original transmission mode. Real-time, high-gain, wide-band, low-noise and low-loss all-optical amplification functions are indispensable key components in the new generation of optical fiber communication systems. With the rapid development of computer networks and other new data transmission services, the demand for communication capacity and system expansion of long-distance optical fiber transmission systems is increasing. However, due to the limitations of their own luminous properti...
