Lanthanide silicate monocrystals useful scintillators for x-ray - and gamma-ray detection.

摘要

The invention relates to the single crystals of silicates of lanthanides, which can be used as scintillators for the detection of x-rays and / or gamma photons. / p & & p & the silicate of lanthanides satisfies the formula: (ln1 - x1 - x2 - x3 ln' x 1 cex 2 tbx 3) 9,33 (sio4) 6 o2 in which ln and ln 'which are different, represent an element chosen from among the rare earth, gd, yb and read and x1, x2 and x3 are such that: 0 = 1 0 x1 = x2 = 0,05 0 = x3 = 0,05 0 x2 + x3 = 0,1 0 x1 + x2 + x3 1 / p & & p & this single crystal is used as a scintillator 1 associated with a photodetector 3 for the detection of x-rays and / or gamma photons.
