Effects of Dimethyl Methylphosphonate on the Triboluminescent Properties of Europium Dibenzoylmethide Triethylammonium

Abstract

In 1966 Hurt et al., synthesized a material that emits a light when fractured so bright that it can be seen in daylight. This unique property is known as triboluminescence. Current uses of triboluminescent materials are for the active element of impact sensors. In 2011, the authors modified the synthesis process of this unique material known as europium dibenzoylmethide triethylammonium (EuD4TEA) which increased the TL by 82 %. In 2012, they discovered that the pure ethanol is not required to produce the best results. In an effort to increase the TL even further, dimethyl methylphosphonate (DMMP) was used as a dopant. This paper will discuss the synthesis process for making EuD4TEA doped with DMMP and its effects on the photoluminescence, triboluminescence, and decay time of EuD4TEA. Results show that DMMP can increase the triboluminescence of EuD4TEA nearly 200 %.
