ABSTRACT
A distinct way to target long-lasting phosphors (LLPs) is disclosed. This new material is a metal-organic framework featuring a 1D zig-zag chain and 3D hydrogen bonded PtS net with three-fold interpenetration. It exhibits persistent luminescence lasting about 1 s which can be traced by the naked eye. The green persistent luminescence is exclusively due to emission from multiple triplet excited states. In this way, LLP can be easily achieved by using a simple hydrothermal synthesis without any codopant that in nature is responsible for well-known inorganic LLPs.
