Abstract

We report the temperature dependence and polarization properties of the zero-phonon lines and broad band emission of the ⁴T₂ → ⁴A₂ emission of Cr³⁺ ions substituting for Zn²⁺ ions in ZnWO₄. The zero-field splitting of the ⁴T₂ state is calculated and compared to the separation of the zero-phonon lines associated with this broad emission band. A molecular orbital (MO) method is used to calculate the polarization properties of the emission. Comparison with experiment suggests that T_2u odd-parity distortion and odd-mode vibrations are most effective in inducing the broad band transition.
