  In solid-state dark matter detectors, energy accumulation due to ionizing
radiation should produce delayed low-energy background similar to the
background produced by energy deposited by mechanical stress. The tunneling
two-level systems model for glasses is missing interactions between excitation;
in contrast, interactions lead to emerging phenomena in Prigogine consideration
of systems with energy flow. We observed energy accumulation and delayed
release as delayed luminescence in sodium iodine and delayed luminescence
suppression by exposure to red light. More studies of fast and delayed
luminescence are required.
