No Data

Main Activator(s) and spectrum:


Most Common Activator: Sm3+

No spectrum for the moment

Comments on activators and spectra:


Sm3+(4f5): Fluorescence spectra are observed from the 4G(4)5/2 to the 6H5/2 (ground state), 6H7/2,6H9/2, and part of the 6H11/2 manifolds. The strongest fluorescence is observed to the 6H9/2 manifold. The distribution of the fluorescence intensities is similar to that observed for the Sm3+-doped glass laser.
