摘要

EuD4TEA 晶体具有一些迷人的特性，例如光致发光和机械致发光。当对 EuD4TEA 晶体进行外部激发时，这两种现象都会出现。光致发光是由外部光辐射激发的，而机械发光则是由施加在其上的外部机械力激发的。EuD4TEA 很容易通过使用二苯甲酰甲烷、六水合硝酸铕和三乙胺的标准结晶法制备。这项研究主要集中在合成 EuD4TEA 晶体的溶剂上。使用的溶剂是乙醇和丙酮。丙酮在某些方面能生产出质量更高的 EuD4TEA 晶体，功不可没。丙酮基最终产品的体积更大，在激发下的发光强度更高。

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

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.
