Luminescent properties of SrS:Ce pellets sintered at 1700 °C were investigated under high pressure. Two different Ce3+-related emissions were confirmed to appear in blue-green and red part of spectrum and were shown to shift significantly and linearly to longer wavelengths with increasing pressure. Changes in decay times of both emissions were also thoroughly analyzed. The results confirmed that Ce3+ ions pairing/clustering occurring due to their enhanced mobility at high temperatures is responsible for the appearance of the recently reported red Ce3+ emission in sintered SrS:Ce pellets.
