Abstract
The lifetime τ of the R1 fluorescence line, 2E(Ē)→4A2 of ruby (Al2O3:Cr3+) has been measured under high‐pressure conditions (up to 42.7 GPa) using a modulation fluorometry technique. This study shows that τ increases linearly with pressure and that this increase is primarily caused by a rapid decrease in the transition probability of the radiative transition. The present measurements agree qualitatively with the theoretically predicted decrease in the oscillator strength at high pressure.This publication has 17 references indexed in Scilit:
