Contribution

The paper presents a new technique for infrared scintillation measurement that allows accurate comparison with known UV-visible scintillation yields.

Findings

Infrared light yield of the tested crystal up to 1700 nm was measured.

The technique enables precise quantification of IR scintillation in rare earth-doped crystals.

Abstract

We propose a new technique to measure the infrared scintillation light yield of rare earth (RE) doped crystals by comparing it to near UV-visible scintillation of a calibrated Pr:(Lu$_{0.75}$Y$_{0.25}$)$_{3}$Al$_5$O$_{12}$ sample. As an example, we apply this technique to provide the light yield in visible and infrared range up to \SI{1700}{nm} of this crystal.
