| dc.description | The electron-phonon coupling for Cr<sup>3+</sup> in different oxide host lattices (MgO, α-Al<sub>2</sub>O<sub>3</sub> and LaAlO<sub>3</sub>) was probed by performing temperature dependent line broadening measurements for zero-phonon emission lines of single ions and exchange coupled pairs. No differences in electron-phonon coupling were found comparing the results for pairs and single ions in α-Al<sub>2</sub>O<sub>3</sub> (3NN and 4NN pairs) and LaAlO<sub>3</sub> (NN pairs). In Cr<sup>3+</sup> doped MgO (Cr<sup>3+</sup>-V<sub>Mg</sub>-Cr<sup>3+</sup> pairs), it was found that the electron-phonon coupling strength parameter is larger for the pairs than for the isolated Cr<sup>3+</sup> ions. This is probably due to changes in the surroundings of Cr<sup>3+</sup> by local charge compensation by a magnesium vacancy, and not to interaction between the Cr<sup>3+</sup> ions. |
