Abstract

본 발명은 다층 전계발광소자에 관한 것으로, 종래 다층 전계발광소자는 형광층을 ZnC층과 SrS층을 번갈아 증착하여 형성하는데, 이 두 물질은 상기 SrS층이 약 1.13Å,ZnS층이 약0.74Å의 이온반경을 갖는다. 따라서 두 층을 적층하는 경우 정합계면을 얻기 힘들어 적층이 완료되면, 계면에서 스트레스(stress)와 필링(peeling)현상이 발생하여 소자가 파괴되는 문제점이 있고, 또한 ZnC층은 500℃에서 증착이 이루어지므로 두 층간에 온도의 상승과 하강에 따른 서멀 스트레스(thetmalstress)가 필링(peeling)현상에 큰 요인으로 작용하는 문제점이 있었다. 본 발명은 이러한 문제점을 해결하기 위하여 다층구조의 형공층을 형성할 시 SrS층과 이온반경차이가 적은 CaS층을 번갈아 적층하여 소자제작시 계면에서의 필링(peeling)현상을 제거토록 하는 다층 전계발광소자를 창안한 것이다.
