Synthesisation of Photo-Mechanoluminescence Crystal of Europium Dibenzoylmethide Triethylamine (EuD4TEA) with Different Solvent

Abstract

EuD4TEA crystals have a few fascinating properties, such as photoluminescence and mechanoluminescence. Both phenomena occur when external excitation is performed on EuD4TEA crystals. Photoluminescence is excited by external light radiation, whereas mechanoluminescence is stimulated by an external mechanical force applied to it. EuD4TEA has easily been prepared only by standard crystallisation using dibenzoylmethane, europium nitrate hexahydrate, and triethylamine. This research mainly focused on the solvent for the synthesis of EuD4TEA crystals. The solvents used were ethanol and acetone. Acetone has the main credit for producing much higher-quality EuD4TEA crystals in certain aspects. Acetone-based end products are larger and have higher light emission under excitation.
