Abstract

Abstract The effect of hydrostatic pressure (varying up to 91 kbar) at room temperature emission spectra and fluorescence lifetime of the Cr 3+ R1 line ( 2E → 4A 2 transition) in tiospinel ZnAl 2S 4 was studied for the first time. The studies performed reveal the shift of the R1 line with increasing pressure. Such a red shift was accompanied by a significant change of the fluorescence lifetime. Both trends were successfully explained by a simple model, which resulted in adequate agreement between the calculated and the observed.
