| titleOfInvention | Yellow long-afterglow luminescent material and preparation method thereof |
| abstract | The invention provides a yellow long-afterglow luminescent material. The yellow long afterglow luminescent material provided by the invention is a yellow long afterglow luminescent material doped with low valence alkali metal ions and high valence rare earth ions, wherein barium gallate is used as a matrix, Bi ions are used as a luminescent center. Compared with the prior art, the long afterglow material of the system is bright, the afterglow time is long, and the afterglow can last for more than 48 hours for the longest time; meanwhile, the long afterglow material has simple preparation process, stable chemical property, fluffiness, easy grinding, no radioactivity and no harm to the environment. |
