Abstract

The crystalline material GSGG:Cr³⁺ is currently of interest as a broad-band, room temperature laser material. The small separation between the ⁴T₂ and ²E electronic levels of Cr³⁺ in this system can result in interesting spectroscopic behaviour. We have investigated the temperature dependence of the CW and transient luminescence and have found it to be consistent with a model for the dominant Cr³⁺ site in which the lowest energy ²E and ⁴T₂ levels are approximately coincident in energy at low temperature.
