The low temperature scintillation properties of LSO:Ce from 4.3 to 300 K were systematically studied and temperature-dependent light yield nonproportionality was measured for the first time. Increasing temperature from 4.3 to 300 K led to increased decay times and light output, an improvement in both the total energy resolution and light yield nonproportionality, and a red shift in the emission. Mechanisms were proposed to explain the complex trends observed in these scintillation properties.
