Abstract

The invention belongs to the technical field of glass, and particularly relates to luminescent glass. The luminescent glass is prepared from the following raw materials in parts by weight: 40 to 70 parts of silicon dioxide, 10 to 22 parts of aluminum oxide, 2 to 8 parts of sodium oxide, 3 to 9 parts of sodium phosphate, 0.1 to 0.7 part of thulium oxide, 0.2 to 1.4 parts of samarium oxide and 0.03 to 0.21 part of neodymium oxide. The luminescent glass disclosed by the invention is high in transparency and high in light efficiency; light rays are uniform, stable, and high in brightness.

Description

technical field [0001] The invention belongs to the technical field of glass, in particular to a luminescent glass. Background technique [0002] As far as the applicant knows, some of the luminous glass currently on the market are embedded with LED lights in the glass, and some are made of hollow glass, and then the LED lights are placed in the hollow layer; the luminous glass products designed by these technical solutions are more dazzling. The light-emitting surface is not uniform enough, there are obvious dark areas, it is not beautiful enough, and maintenance is very troublesome. [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 before coating, and necessary heat treatment is required after coating, which leads to a decrease in the luminescent performance of pho...
