Europium-doped dibenzoylmethide triethylammonium (EuD4TEA) has been known as an organic mechanoluminescent (ML) material. In the present study the ML properties are investigated for the EuD4TEA with an addition of polyvinylpyrrolidone (PVP). For the first time novel organic ML material has been successfully synthesized by controlled slow cooling method at very low temperature of 70 C. The ML properties are characterized by using Hamamatsu Photonic Multichannel Analyzer (PMA). The ML spectrum corresponds to the europium D0 to fn transition. The results suggest that the addition of PVP enhances ML intensity of EuD4TEA. Effect of the addition will be discussed in detail.
