Problems solved by technology

[0003] However, it is difficult to obtain heavy metal oxide glasses by conventional container-based preparation methods, mainly because the heavy metal oxide melts connected by ionic bonds are easily rearranged during cooling, resulting in most of the heavy metal oxides having poor amorphous Formability, it is difficult to obtain glass blocks under normal conditions
It is precisely because of the above reasons that the development and application of heavy metal oxide luminescent glass materials are limited.

Embodiment 1

[0037] According to the formula Ti 2.25 La 0.78-x Gd x Er 0.04 Yb 0.18 o 6 , (x=0.10) Weigh the corresponding oxides and mix them uniformly. Then the mixed powder was sintered at 800°C for 12 hours in the air, and then cooled down naturally. Then, the sintered powder is pressed into tablets by a tablet machine at a pressure of 7 MPa, and pressed into a disc shape of 90-100 mg. Finally, it was melted and solidified in an air suspension furnace without a container. The throat diameter of the nozzle was 2mm, the laser power was 100w, and the holding time was 4 minutes. The gas used to achieve air suspension was air, and the pressure was 7MPa. Finally, block titanic acid was obtained. Lanthanum-based glass.

Embodiment 2

[0039] According to the formula Ti 2.25 La 0.78-x Gd x Er 0.04 Yb 0.18 o 6 , (x=0.15) Weigh the corresponding oxides and mix them uniformly. Then the mixed powder was sintered at 800°C for 12 hours in the air, and then cooled down naturally. Referring to Example 1, the bulk lanthanum titanate-based glass was finally obtained by pressing into tablets and laser melting.

Embodiment 3

[0041] According to the formula Ti 2.25 La 0.78-x Gd x Er 0.04 Yb 0.18 o 6 , (x=0.20) Weigh the corresponding oxides and mix them uniformly. Then the mixed powder was sintered at 800°C for 12 hours in the air, and then cooled down naturally. Referring to Example 1, the bulk lanthanum titanate-based glass was finally obtained by pressing into tablets and laser melting.

Abstract

The invention relates to a green-light upconversion lanthanium titanate-based paramagnetic glass material and a preparation method thereof. The green-light upconversion lanthanium titanate-based paramagnetic glass material is prepared from the following compositions through the following method: (1) introducing a magnetic composition Gd2O3 into a lanthanium titanate-base material; and (2) mixing powders of various oxides forming the green-light upconversion lanthanium titanate-based paramagnetic glass material, performing melting and solidification in an air-suspending container-free furnace, so as to prepare the green-light upconversion lanthanium titanate-based paramagnetic glass material. The green-light upconversion lanthanium titanate-based paramagnetic glass material also possesses good mechanical strength, thermal performance and relatively low phonon energy, and possesses wide application prospect in fields of short-wavelength laser devices, optical waveguide, information storage and the like.

Description

technical field [0001] The invention relates to a green light up-conversion luminescent glass material, in particular to a green light up-conversion lanthanum titanate-based paramagnetic glass material, which belongs to the technical field of luminescent materials. Background technique [0002] With the rapid development of technologies such as information processing, data storage, video display, and laser medicine, there is an increasing need for high-efficiency, high-performance laser light sources with visible wavelengths, especially blue-green wavelengths. At present, the use of rare earth ions to upconvert luminescence to obtain blue-green light output has attracted much attention. Compared with rare earth doped single crystals, rare earth ion doped glasses have short manufacturing cycle, easy processing, and wide tunable range. It is considered to be a new type of up-conversion luminescent material with excellent performance and wide application prospects. Generally, ...
