| Abstract: | Abstract The optical absorption spectra of Nd3+ ion in glutamic, L-aspartic and maleic acids in UV-VIS and NIR regions have been recorded. From the spectral data thus obtained, various spectroscopic parameters are evaluated. The radiative lifetimes (γR) and branching ratios (β) for the excited states of Nd3+ ion in three acids have been computed. The relationship between the environment sensitive Judd-Ofelt parameter (ω2) and the intensities of hypersensitive level (4G5/2) is in good coincidence following the Judd-Ofelt theory. |
