Abstract

A systematic and comparative study of luminescence and optical absorption properties of the trivalent rare earth neodymium ion in the Bi4Ge3O12 and Bi12SiO20 crystal lattices is presented. The incorporation of Nd3+ ions intothese crystals is more easily achieved in the first one than in the latter. In both matrices their intrinsic emission gives rise to a radiative energy transfer between the host and the impurity ion. On the other hand most ofthe Stark energy levels have been identified for both matrices. A calculation of the Ohm (2), Ohm (4) and Ohm (6) Judd-Ofelt parameters is given for each crystal.
