Abstract

The technique of laser-induced fluorescence line narrowing is used to probe the inhomogeneously broadened ²E-⁴A₂ transition of Cr³⁺ in the disordered crystalline material α-Al_2xGa_2(1-x)O₃ where x=0.2. The observed emission from Cr³⁺ ions in specific local environments is consistent with that from Cr³⁺ in the ordered materials α-Al₂O₃ and α-Ga₂O₃. Measurements of the homogen eous linewidth at various temperatures indicate that the broadening mechanism associated with the tunneling modes of amorphous structures is not present in this material.
