Electroluminescence in Alkali Halide Crystals
The electroluminescence of alkali halide crystals was investigated at liquid nitrogen or lower temperatures. The effect is obtained with time varying electrical excitation and can he attributed to electron-hole radiative recombination. It is localized to a thin interface layer near the metal contact. The luminescence can be described by avalanche breakdown theory.
