Graphene과 TiO2를 첨가하여 스크린 프린팅으로 제작한 ZnS 복합물 무기전계발광소자의 광특성에 관한 연구

Abstract

ZnS:(Cu,Al) AC powder electroluminescence devices have been fabricated by screen printing method. BaTiO3 was used at the dielectric material. The fabrication of the device has been made by manual screen printing on a variety of variables, the optimal condition was obtained from many experiences. TiO2 has an acid resistance and an alkali resistance. TiO2 is harmless to human body and most often used in the photocatalyst. Graphene has high physical and chemical stability and higher performance to the display industry. In this study, we try to use TiO2 and Graphene additive to increase an efficiency of the inorganic EL device. Comparison of characteristics according to the structure of the device was carried out by measurement in cross sectional SEM image, XRD image, emission spectrum.
