Abstract: front page image
(EN)A silicate luminescent material and the production method thereof are provided. The chemical formula of the silicate luminescent material is Re4-xTbxMg3SiO13, wherein Re is at least one element selected from the group consisting of Y, Gd, La, Lu and Sc, and 0.05≤x≤1. The silicate luminescent material has short afterglow of 2.13ms, and it can emit strong green light under the vacuum ultraviolet excitation. Additionally, the silicate luminescent material has stable physical and chemical properties. The production method for producing the silicate luminescent material is simple and cost-efficient.
(FR)Matériau luminescent à base de silicate et son procédé de production. La formule chimique du matériau luminescent à base de silicate selon l'invention est Re4-xTbxMg3SiO13, Re étant au moins un élément choisi dans le groupe constitué par Y, Gd, La, Lu et Sc, et 0,05≤x≤1. Ce matériau luminescent à base de silicate a une incandescence résiduelle courte de 2,13 ms, et il peut émettre une forte lumière verte dans des conditions d'excitation ultraviolette sous vide. De plus, il possède des propriétés physiques et chimiques stables. Le procédé de production utilisé pour produire le matériau luminescent à base de silicate selon l'invention est simple et rentable.
