We define, for each quasi-syntomic ring (in the sense of Bhatt-Morrow-Scholze), a category of \textit{admissible prismatic Dieudonné crystals over } and a natural functor from -divisible groups over to . We prove that this functor is an antiequivalence. Our main cohomological tool is the prismatic formalism recently developed by Bhatt and Scholze.
