Abstract

The invention discloses a bifunctional glass and a preparation method thereof. The preparation method includes: firstly, in terms of molar percentage, placing 10-18% of Ga2O3, 15-28% of SiC, 14-25% of B2O3, 1-3% of GeO2, 5-40% of Eu2O3, 5-30% of Tb2O3, and 0.1-2% of CeO2 into a ball mill to conduct ball-milling till being able to pass a 200-mesh stand sieve, thus forming a batch; and then subjecting the batch to high temperature melting in air atmosphere into molten glass, finally pouring the molten glass in a graphite mold to undergo forming, and then carrying out precise annealing to obtain the bifunctional glass. The bifunctional glass prepared according to the invention has high light transmittance, strong magnetism, high luminescent intensity, high brightness, pure chroma, high quenching concentration and temperature, excellent glass forming properties, excellent thermal stability and chemical stability. And the preparation process is easy to operate, thus being suitable for industrialized production.

Description

technical field [0001] The invention relates to a dual-function glass and a preparation method thereof. Background technique [0002] Luminescence is a phenomenon in which an object directly converts the energy absorbed within it into non-equilibrium radiation. When a certain substance is excited, if the substance does not undergo chemical changes, it will always return to its original equilibrium state. A portion of the excess energy is released in the form of light or heat. If it is emitted in the form of electromagnetic waves such as visible light, this phenomenon is called luminescence. The substance that emits light after excitation is called a luminescent material or a phosphor. The luminescent material is composed of a matrix and an activator, and a sensitizer is also incorporated in some materials to improve the luminescent performance. Although luminescence is a macroscopic phenomenon, it is closely related to microscopic processes such as defect structure, ener...
