摘要：
Optical properties of Pr3+ ions in gadolinium calcium oxoborate Ca4GdO(BO3)(3) (GdCOB) nonlinear crystals have been studied. Polarized absorption and emission spectra and fluorescence lifetime measurements have been performed and discussed using modified Judd-Ofelt theory. The system is characterized by intense red emission at 610 nm corresponding to the D-1(2) --> H-3(4) transition, no emission from the excited P-3(0) State has been observed. D-1(2) emission has been investigated under pulsed excitation and the experimental lifetimes for this level has been compared with this obtained theoretically by using Judd-Ofelt approach.
