Abstract :
The scintillation properties of Ce3+ and Pr3+ doped complex fluoride crystals of composition CsGd2F7:Ce3+, Pr3+ and K2YF5:Ce3+, Pr3+ and of Pr 3+ doped Y3Al5O12:Pr3+ single crystals are studied by means of X-ray and gamma ray excitation. The Ce3+ and Pr3+ doped fluoride crystals show 5d-4f luminescences at wavelengths near 340 nm and 240 nm, respectively. 5d-4f luminescence of Pr3+ doped Y3Al5O12 is observed between 300 and 400 nm. The absolute light yield in photons/MeV is presented together with results from scintillation decay time experiments
