Název v původním jazyce

Light yield and light loss coefficient of Pr3+ doped Y3Al5O12 crystals with different Pr3+ concentration under excitation with alpha- and gamma-rays

Popis výsledku v původním jazyce

Light yield (LY) and its ratio under excitation with alpha- and gamma-rays (alpha/gamma ratio) were measured for Y3Al5O12:Pr (YAG:Pr) single crystals with Pr concentration of 0.16, 0.33 and 0.65 wt%. YAG:Pr (0.33 wt%) showed a highest LY value of 14,900 ph/MeV at 662 keV gamma-rays, while a highest LY value of 3,700 ph/MeV at 5.499 MeV alpha- particles was measured for YAG:Pr (0.65 wt%) one, showing a highest alpha/gamma ratio of 0.26. A clear separation was observed for 5.155, 5.486 and 5.806 MeV alpha- particles from a mixed tri-nuclides alpha source. Light yield dependence on sample height was measured under excitation with alpha - rays and the light loss coefficient was estimated and compared to the value measured for the LuAG:Pr sample with comparable size and Pr concentration.
