Abstract

Abstract: Long‐persistent luminescence (LPL) materials have a wide range of applications, such as in architectural decorations, safety signs, watch dials, and glow‐in‐the‐dark toys. Present LPL materials based on inorganics must be processed into powders and blended with polymer matrices before use. However, micropowders of inorganic LPL materials show poor compatibility with common polymers, limiting the mechanical properties and transparency of the composites. Here, a polymer‐based organic LPL (OLPL) system that is flexible, transparent, and solution processable is reported. Following low‐power excitation at room temperature, this polymer‐based OLPL system exhibits LPL after phosphorescence from the donor. Abstract : Polymer‐based organic long‐persistent luminescence (OLPL) in a flexible, transparent, and solution‐processable system is reported. Following low‐power excitation at room temperature, this polymer‐based OLPL system exhibits LPL after the decay of initial phosphorescence from the donor.
