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 f_n transition. The results suggest that the addition of PVP enhances ML intensity of EuD₄TEA. Effect of the addition will be discussed in detail.
