Energy Level Structure-Band Intensities of Pr(NO₃)₃6 H₂O: Organic Acids

Abstract

Analysis of the spectra of Praseodymium nitrate mixed with organic complexes such as Glutamic, l Aspartic and Maleic acids has been carried out from UV to NIR regions. About six energy levels for Pr³⁺ in all the three hosts have been measured and assigned to the appropriate electronic transitions. By applying the Judd-Ofelt theory, the absorption band intensities and lifetimes of the electronic states ³P_1,0 and ¹D₂ have been computed theoretically.
