Creators

Description

The rare earth silicate has the following formula: (Ln1-x-y-zLn'xCeyTbz)9.33 (SiO4)6O2 where Ln and Ln' are different and represent La, Gd, Yb and Lu, x, y and z are chosen with 0<x<1, 0<y<0.05, 0<z<0.05, 0<y + z<0.1 and 0<x + y + z<1. The monocrystal is used as scintillator associated to a photodetector for X and/or gamma rays detection

Abstract (French)

Le silicate de lanthanides repond a la formule: (Ln1-x-y-zLn'xCeyTbz)9.33(SiO4)6O2 dans laquelle Ln et Ln' qui sont differents, representent un element des terres rares choisi parmi La, Gd, Yb et Lu, et x, y et z sont tels que: 0≤x<1 0≤y≤0,05 0≤z≤0,05 0<y + z≤0,1 0<x + y + z<1. Ce monocristal est utilisable comme scintillateur associe a un photodetecteur pour la detection des rayons X et/ou gamma
