Luminescence properties and gamma-ray response of the Ce and Ca co-doped (Gd,Y)F3 single crystals
چکیده انگلیسی
The Ca0.5% and Ce1%, 3%, 7%, 10% co-doped Gd0.5Y0.5F3 single crystals were grown by the μ-PD method. In the Ca0.5% and Ce3% co-doped sample, Ce3+-perturbed luminescence at 380 nm was observed with 32.4 ns photoluminescence decay time. The energy transfer in the sequence of the regular Ce3+→ (Gd3+)n→ the perturbed Ce3+ sites was evidenced through observation of decay time shortening of the regular Ce3+ and Gd3+ centers and the change between the Gd3+ and Ce3+-perturbed emission intensity. The gamma-ray excited scintillation response of the Ca0.5%, Ce7% co-doped Gd0.5Y0.5F3 sample was investigated with the help of the pulse height spectra and the light yield, energy resolution and non-proportionality was evaluated in the interval of energies of 59.4-1274 keV.
