Eu-Based Coordination Polymers Micro-Flowers: Preparation and Luminescence Properties

Flower-like europium (Eu)-based coordination polymer (CP) is successfully synthesized via a facile hydrothermal route, in order to obtain highly luminescent lanthanide complexes, 3,4,5,6-tetrafluorophthalic acid (H2TFA) is used as organic linker. During the reaction, the morphologies of products vary while controlling the reaction time and reactants ratio. Based on the above experiments, a possible growth mechanism is proposed. In addition, the luminescence properties, including luminescence intensity, luminescence lifetime and luminescence quantum yield of the Eu-based CPs are systematically investigated.
