A neodymium doped Ca 5 (BO 3 ) 3 F single crystal with size up to 51×48×8 mm 3 has been grown by the top seeded solution growth (TSSG) technique with a Li 2 O‐B 2 O 3 ‐LiF flux. The spectra of absorption and fluorescence were measured at room temperature. According to Judd‐Ofelt (J‐O) theory, the spectroscopic parameters were calculated and the J‐O parameters Ω 2 , Ω 4 , Ω 6 were obtained as follows: Ω 2 = 1.41×10 −20 cm 2 , Ω 4 = 3.18×10 −20 cm 2 , Ω 6 = 2.11×10 −20 cm 2 . The room temperature fluorescence lifetime of NCBF was measured to be 51.8 μs. According to the J‐O paramenters, the emission probabilities of transitions, branching ratios, the radiative lifetime and the quantum efficiency from the Nd 3+ 4 F 3/2 metastable state to lower lying J manifolds were also obtained. In comparasion with other Nd‐doped borate crystals, the calculated and experimental parameters show that NCBF is a promising SFD crystal.
