N2 - (NaxCa1-2xLux)F2 (x=1/6, 1/4, 1/3) and (NaxCa1-x-yLuy-0.05Ce 0.05)F2y-x (x=0.32, y=0.43) single crystals were grown from the melt using the precise atmosphere controlled type Micro-Pulling-Down (μ-PD) method to investigate their potential as a host material of scintillators. The grown crystals were of single-phase with fluorite-type structure (Fm-3m, Z=4) as confirmed by XRD. The crystals demonstrated 6090% transmittance above 200 nm wavelength and their absorption edges were approximately 145155 nm. Their densities were 4.55.3 g/cm3, and their effective atomic numbers were 56.761.4. Ce doped sample demonstrated better scintillation properties compared to Ce doped CaF2, such as higher light yield and shorter decay time.
