Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] A Ho 3+ Doped ZBYA fluoride glass that can produce fluorescence in the mid-infrared band near 3.9 μm, including the following:

[0020] Ho 3+ Preparation of ion-doped ZBYA fluoride glass:

[0021] Weigh the high-purity raw materials according to the following mole percentages, and mix them thoroughly in the grinding bowl;

[0022] 50ZrF 4 –49-x (BaF 2 –YF 3 –AlF 3 )–xHoF 3 (x=0.1,0.2,0.5,1,2,3,4,5,7,9)

[0023] glass melting

[0024] Put the mixture in a platinum crucible with a lid, melt it in a high-temperature furnace in a glove box at 850°C, then place the molten glass on a preheated brass mold, and place it in an annealing furnace for annealing at 320°C to eliminate the glass The stress generated in the process to obtain the final glass sample.

Abstract

The invention provides Ho<3+> doped ZBYA fluoride glass. The molar percentage of the concentration of the raw materials to the concentration of the doping ions is 50ZrF4-33BaF2-(10-x)YF3-7AlF3)-xHoF3(x=0.1, 0.2, 0.5, 1, 2, 3, 4, 5, 7, 9). The preparation method comprises the following steps: weighing the high-purity raw materials according to the proportion; putting the mixture into a platinum crucible, putting the platinum crucible into a high-temperature furnace (850 DEG C) in a glove box for melting; pressing the molten glass into a precursor glass sample; placing the sample in an annealing furnace for an annealing treatment so as to eliminate stress in the glass, and cooling to the room temperature to obtain Ho<3+> doped ZBYA fluoride glass. The provided glass generates farthest 3.9 [mu]m mid-infrared band fluorescence under the excitation of 888 nm laser, and the wavelength has an important application value in the fields of spectroscopy, remote sensing, medical treatment, environmental protection, military affairs and the like.

Description

technical field [0001] The invention relates to a ZBYA fluoride glass, in particular to a Ho 3+ Doped ZBYA fluoride glass. Background technique [0002] Mid-infrared (2-20μm) lasers are located in the vibration-rotation energy level absorption bands of many gas molecules and organic molecules, the so-called "molecular fingerprint area". Therefore, mid-infrared lasers are used in disease diagnosis, trace gas detection, molecular spectroscopy and other fields. It has important application prospects. In addition, there are three transparent "windows" in the space atmosphere, which are 2-2.7 μm, 3-5 μm and 8-13 μm respectively. Therefore, mid-infrared lasers also have important application potential in remote sensing, space communication and military fields. At present, laser technology in the visible and near-infrared bands has developed maturely, but the development of mid-infrared lasers, especially mid-infrared lasers in the 3 μm and above bands, is very slow. In practica...
