More Information
Summary:The single crystal is in the form of a mixed crystal of the general formula Gd3-xCexAl5Sc2O12, where 0.01 < x </= 0.1 and 1.80 < y </= 2.0, preferably having a melt composition of the formula Gd2.97Ce0.03Al3Sc2O12. The single crystal is suitable as a scintillation crystal for the simultaneous detection of low-energy electromagnetic radiation (K X-rays), for the detection of higher-energy electromagnetic radiation ( gamma -quanta) and for the detection of neutrons and charged particles ( alpha - and beta -particles)
