N2 - Micro-pulling-down (μ-PD) growth apparatus was modified for fluoride crystals. PrF3 was grown with various concentrations of Ce 3+ from 0-100%. The crystals were transparent and colorless (CeF 3) or greenish and 3mm in diameter and 15-50 mm in length. Neither visible inclusions nor cracks were observed. Radioluminescence spectra and decay kinetics were measured for the sample set at room temperature. In comparison to the Czochralski or Bridgman method, the μ-PD method allows to produce single crystalline material in a faster thus more economic way. Once it is established for the fluoride crystals, it is an efficient tool for exploring the field of new functional fluorides.
