Abstract

A coincidence in energy of the ²E and ⁴T₂ excited levels of Cr³⁺ appears to occur in the material GSGG:Cr³⁺, and as a result the material exhibits a number of interesting luminescence features. The mixing of the ²E and ⁴T₂ eigenstates by the spin-orbit coupling operator is analyzed using a simple model which takes account of the vibrational nature of the eigenstates. It is shown that this model is capable of explaining many of the observed luminescence features of the material.
