Transition intensities of trivalent lanthanide ions in solids: Revisiting the Judd-Ofelt theory

Gohar Hovhannesyan, Vincent Boudon, Maxence Lepers

We present a modified version of the Judd-Ofelt theory, which describes the intensities of f-f transitions by trivalent lanthanide ions (Ln${}^{3+}$) in solids. In our model, the pro…
