【 摘 要 】

The growth of Nd³⁺ doped lithium niobate crystals using Bridgman method has been reported in this paper. By means of the optimum conditions such as proper feed materials, sealed platinum crucibles, growth rate of 1â€�??1.5 mm/h and temperature gradient of 30â€�??35°C/cm across the solidâ€�?�liquid interface under the furnace temperature of 1300°C, single crystals containing Nd³⁺ ion with 0.54 mol% concentration were obtained. X-ray diffraction and ICPâ€�?�AES were used to characterize the crystals and its composition. The absorption, emission and fluorescence lifetime are also measured. Based on the Juddâ€�?�Ofelt theory, we obtained the optical parameters of the crystal such as the luminescent quantum efficiency, the radioactive lifetimes, the branching ratios and the emission cross-section.
