## Abstract

Applications that utilize scintillation detectors at low temperatures are growing in number. Many of these require materials with high light yield and a fast response. Here we report on the low-temperature characterisation of ZnSe doped with Al or Te, respectively. The X-ray luminescence and decay curves were measured over the 77- 295 K temperature range, and alpha particle excitation was used to examine scintillation light output and decay kinetics over the range 9-295 K. A significant improvement of the scintillation characteristics was observed at cooling below 100 K. The scintillation light yield of the crystals increases by a factor about two, and the decay time constant decreases by almost an order of magnitude to 0.3-0.4 microsec. These improvements enhance the potential of ZnSe-based crystals for application in cryogenic scintillation detectors of ionising radiation.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
