Anotace	The luminescence and scintillation properties of Gd1.53La0.47Si2O7:Ce (GPSLa23.5%:Ce) scintillators were investigated and compared to those of Lu1.9Y0.1SiO5:Ce (LYSO:Ce) scintillators. At 662 keV γ-rays, the light yield of 33,500 ± 3300 ph/MeV obtained for GPSLa23.5%:Ce is higher than that of 28,100 ± 2800 ph/MeV obtained for LYSO:Ce. The energy resolution of 4.8 ± 0.2% obtained for GPSLa23.5%:Ce is much better than that of 8.2 ± 0.3% obtained for LYSO:Ce due to its better intrinsic resolution and proportionality of light yield. The light yield and energy resolution for α- rays, as well as a light yield ratio under excitation with α - and γ - rays (α/γ ratio) were also determined. The intrinsic light yield and light loss coefficient under excitation with 662 keV γ-rays were evaluated.
