Spectroscopic parameters calculation of Nd3+ in LaMgAl11010 crystal using Judd-Ofelt theory |
| |
| Abstract: | The calculation formula of the spectroscopic intensity parameters, such as line intensity, oscillator strengths (fij),intensity para-meters Ω(2,4,6), transition probability of electron dipole and branch ratio, are derived by using Judd-Ofelt theory. According to the results of measuring the absorption and fluorescence spectra of Nd3+ in LaMgAl11010crystal, these parameters are calculated and well accordant with several methods. |
