Abstract

0.1%, 0.5%, 1% and 3% Ce doped scintillation crystals based on NaF-CaF 2-LuF3 solid solutions were grown from the melt using Micro-Pulling-Down (μ-PD) method. The grown crystals were transparent and their transmittance was approximately 80% for the wavelengths longer than 320 nm. Concerning the scintillation properties, radio-luminescence peaks of the crystals were detected at approximately 330 nm. The light yield of the crystals was also measured using γ-ray (137Cs and 22Na) as the excitation source.
