Received Date: 4 December 2023
Revised Date: 4 February 2024

Recently, mechanoluminescence materials have attracted considerable attention due to their unique optical properties induced by external stimulus, demonstrating the excellent potential for sensing impact, stress, tension, pressure, display and lighting, and imaging. Using dibenzoylmethane (DBM), Eu(NO₃)₃, and triethylamine (TEA) as raw materials, the ionic Eu³⁺ coordination complexes Eu(DBM)₄TEA were obtained. The complexes were characterized by UV-vis absorption spectroscopy, infrared spectroscopy, X-ray diffraction, and solid fluorescence. Their mechanoluminescence properties are realized by grinding the sample powder. The designing experiment is developed based on the research results and consists of the synthesis and characterization of lanthanide-based organometallic materials. This experiment with a simple route includes a lot of knowledge and was beneficial to enhance students’ research capabilities, helping students learn the relationship between structure and function, and getting scientific research training.
