Abstract

The use of thermally activated luminescent processes in some crystalline materials for thermal infrared-to-visible conversion is examined. Such processes are illustrated by the experimental behavior of a Eu³⁺-doped crystalline terbium chelate at cryogenic temperatures. The calculated sensitivity of infrared image converters making use of this phenomenon is of the order of 10⁻¹⁵ J per image element, depending on the resolution of the optical system.
