Electroluminescent device and method for fabricating same

摘要

An electroluminescent device improved in brightness includes sequentially stacked layers having an optically transparent material on at least the viewing side of the structure and has a luminescent layer based on a Group II-III-VI compound host material with an element acting as a luminescent center added therein, wherein a Group II element having an ion radius differing from that of the Group II element constituting the compound host material is further added in the luminescent layer.
