Abstract
[Ca24Al28O64]4+(4e–) is a new inorganic electride, which is air‐stable even at ∼ 300 °C. Its electron field‐emission properties originate from electron anions encaged in subnanometer‐sized cages embedded in its crystal structure, and the emission current is controlled by Fowler–Nordheim field emission at high electric fields (see Figure). Field‐emission display devices demonstrate bright light emission clearly visible under ambient light (inset).Keywords
