Study on wide-area inorganic electroluminescence devices driven by current injection

为了制造电流注入驱动的广域无机电致发光器件，研究了有效的载流子注入结构和对发射层的改进。对于前者，虽然实际上没有实现有效的载流子注入结构，但在单晶ZnS中掺杂n受体和银，实现了同质-pn结，取得了积极的结果。对于后者，通过铝的共掺杂改善了掺杂铜的多晶ZnS的光学性能。

In order to fabricate wide-area inorganic electroluminescence devices driven by current injection, effective carrier injection structures and improvement of the emission layer have been studied. For the former, although effective carrier injection structures are not actually realized, positive results have been obtained in doping single-crystal ZnS with N-acceptor and silver for the realization of homo-pn-junction. For the latter, optical properties of poly-crystal ZnS doped with copper have been improved by co-doping of aluminum.
