Abstract

The invention discloses rare-earth-doped glass of with near-infrared dual waveband ultra wide band emission and a preparation method of the rare-earth-doped glass. The rare-earth-doped glass is prepared from the components that 74-74.9 mol% of TeO2, 14.5-15 mol% of ZnO, 4.5-5 mol% of WO3, 4.5-5 mol% of Bi2O3, 0.01-0.5 mol% of Pr6O11, 0.01-0.1 mol% of Nd2O3 and 0.01-0.4 mol% of Er2O3; and the rare-earth-doped glass has the advantages that two near-infrared band ultra wide bands and relative flat optical emission in the wavelength range of 800-1100 nm and 1250-1650 nm can be simultaneously achieved, the prepared glass is stable, and the physical and chemical properties are excellent.

Description

technical field [0001] The present invention relates to a rare-earth-doped glass used in the fields of medical imaging and optical fiber communication and its preparation technology, in particular to a near-infrared dual-band ultra-broadband emission rare-earth-doped glass and a preparation method thereof. Glass is rare earth Pr 3+ -Nd 3+ -Er 3+ Ion-doped tellurite glass. Background technique [0002] Near-infrared light sources have very important applications in many fields such as medical imaging, laser surgery, photovoltaic cells, component analysis, atmospheric remote sensing, and optical fiber communications. For example, in medical imaging, the 1.0μm near-infrared band is often referred to as the "biological window" of human tissue, because lasers in this wavelength range can penetrate deeper into biological tissue compared with ultraviolet and visible light bands. The 1.53μm near-infrared band is called the third communication window, which is located in the lowe...
