Pr1%:K(Y1-xLux)3F10 (x=0, 0.2, 0.4) single crystals were grown by the μ-PD method. All the grown crystals were greenish and perfectly transparent without any inclusions or cracks. Radioluminescence spectra and decay kinetics of the Pr1%:K(Y,Lu) 3F10 crystals were measured. Emission from the Pr 3 5d4f transition, peaking around 260 nm and of the decay time of around 22 ns were observed. The 5d4f emission intensities of the Pr1%:K(Y,Lu)3F10 crystals were higher than that of the standard BGO scintillator.
