Abstract
In this study we introduce a two-step strategy for the synthesis of BaAl2S4:Eu bulk samples. The first step involves synthesis of a BaS:Eu intermediate by a sol-gel/polymerizable complex method, which provides a highly homogenous distribution of Eu in the BaS. The second step involves solid-state reaction between the BaS:Eu intermediate with Al2S3 in an ampoule at high temperature. It was found that phase purity increases with increasing synthesis temperature and almost single-phase samples can be obtained at above 900°C. However, BaAl2S4:Eu samples synthesized at lower temperatures produced more intense emission. To the best of our knowledge, this is the first time a solution method has been used in the preparation of BaAl2S4:Eu.
