Temperature-dependent emission spectra of Sm[2+]-doped SrMgF4 have been obtained in the temperature range from 50 to 300 K. At 50 K, six bands are observed for the very strong [5]D0→[7]F0 transition, in agreement with the reported sixfold crystal superstructure. The overall splitting of more than 70 cm[−1] highlights the important structural differences of the six Sr sites. Upon heating progressively to room temperature, the spectra change progressively with a more pronounced change between 270 and 300 K. These observations suggest the possibility of a complex structural behavior for SrMgF[4] which will require new experiments.
