The fluorescence spectrum of BeAl6O10:Cr crystal consists of seven narrow lines and a broad b and. The difference between the lifetimes of the broad band and the lines is very big even at room temperature. There is less relationship between the band emission and the line emissions in BeAlGO10:Cr, unlike in BeAl2O4:Cr. To identify the Cr centers, experimental study has been carried out. Based on the temperature-and the concentration dependence of the line intensities, we suggest that three mainlines result from two types of single or oeniers, and other two linee oome from Cr pairs centers.
