Abstract

The invention relates to a luminous glass and a manufacturing method thereof. The luminous glass is rare earth ion-doped silicate luminous glass; the structural formula of the luminous glass is aM2O.cSiO2.dRe2O3.zE, wherein M is alkali metal, E is conductive metal oxide, and Re is at least one rare earth element; and the luminous glass comprises 25 to 50 mole parts of M2O, 30 to 70 mole parts of SiO2, 0.001 to 20 mole parts of Re2O3 and 0.034 to 14 mole parts of E. Because the conductive metal oxide component is added into the luminous glass, the luminous performance of the luminous glass under cathode rays is remarkably improved by using the conductive performance of the conductive metal oxide component compared with the luminous glass which is not added with the conductive component, and the luminous efficiency of the luminous glass is improved.

Description

technical field [0001] The invention relates to the technical field of luminescent materials, in particular to a luminescent glass and a manufacturing method thereof. Background technique [0002] In recent years, light-emitting devices such as field emission devices have attracted much attention due to their advantages such as low operating voltage, low power consumption, no need for deflection coils, no X-ray radiation, and resistance to radiation and magnetic field interference. The combination of field emission cathodes and luminescent materials can obtain high Field emission light source with high brightness and high color rendering can be used in display, various indications, general lighting and other fields. [0003] In traditional light-emitting devices, the light-emitting materials used generally include phosphors, nanocrystals, and glass. At present, low-voltage phosphors are mainly used as luminescent materials. However, phosphors need to be crushed and washed b...
