MONOCRYSTALS OF LANTHANIDE SILICATES AS SCINTILLATORS FOR THE DETECTION OF X-RAY AND GAMMA RADIATION

摘要

The invention relates to monocrystals of lanthanide silicates, which can be used as scintillators for the detection of X and / or gamma rays. The lanthanide silicate has the formula: (Ln1-x1-x2) where Ln and Ln ', which are different, represent a rare earth element chosen from La, Gd, Yb and Lu, and x1, x2 and x3 are such that: 0 = x1 1 0 = x2 = 0,05 0 = x3 = 0,05 0 x2 + x3 = 0,1 0 x1 + x2 + x3 1 / This single crystal can be used as a scintillator 1 associated with a photodetector 3 for the detection of X and / or gamma rays. / P
