Self-absorption of the Eu2+ emission is an important aspect in SrI2:Eu that affects its scintillation
performance. To calculate the probability of self-absorption, we measured the light yield and the decay
time of 1–15 mm thick SrI2:2%Eu samples at temperatures between 78 K and 600 K. The obtained
properties of SrI2:2%Eu crystals were then compared to those of SrI2:5%Eu. The decay times of SrI2:5%Eu crystals were the same or somewhat longer compared to those of twice as thickSrI2:2%Eu crystals. Accordingly, doubling the thickness has the same effect on the probability of self-absorption as
doubling the Eu concentration.
