Optical Transitions in Cr Doped Bi4Ge3O12 Crystal
-
Abstract
In this paper, we present the results of the optical absorption spectra of Cr doped Bi4Ge3O12 crystal at room temperature and compare them with the theoretical results of a multifold scattering (MS)-Xα calculation which include the energy-level structures and the transition energies of Cr3+ and Cr4+ located in Ge-site in the crystal.
