Paper Abstract

Europium-doped barium thioaluminate based on BaAl2S4: Eu is currently the most efficient blue phosphor for inorganic thin film electroluminescence. Many researchers and experts have been investigating on this material and have also got great achievements. The phosphors exhibit EL luminescence up to 900cd/m2, peak efficiency over 1 lm/W, and long life time of 30 thousand hours, which is sufficient to TV display application. In this work we will review the experimental research process of the fabrication on the BaAl2S4:Eu phosphor layers, introduce the four main methods of fabricating the blue emitting phosphors: two targets pulse electron beam evaporation; four targets pulse electron beam evaporation; two targets sputter deposition and one target sputter deposition. Finally we will also summarize the principal conclusions drawn from those experiments mentioned above, which will be beneficial to our research in the future.
