| Abstract: | The spectral parameters of Nd3+ ions in Nd3+-doped NaGd(MoO4)2 crystal have been investigated based on Judd-Ofelt theory and obtained as follows: The intensity parameters Ωeff are Ω2 = 24.77×10-20, Ω4 = 7.31×10-20 and Ω6 = 6.91×10-20 cm2. The radiative lifetime is 100μs, and the quantum efficiency is 93.9%. The fluorescence branch ratios were calculated to be β1 = 0.441, β2 = 0.469, β3 = 0.086 and β4 = 0.004. |
