Make crystals GLOW SMASH!

In this video you triboluminescent or Smash-glow crystals. Triboluminescence is the phenomenon in which light is produced when something is rubbed or broken. The exact mechanism is still under investigation by triboluminescence works, but the best theories to propose that the breakage of the structure causes charge separation of the energy of free recombination. This energy is collected from nearby atoms, in this case, europium, and released as a light depending on their ionizationor fluorescence spectra. Many substances exhibit triboluminescence, like sugar and tape. But tetrakis europium (Dibenzoylmethide) triethylammonium is one of the strongest, and its glow can be easily captured by a camera. It is prepared by mixing 100 ml of ethanol, 2.93g of europium dibenzoylmethane fact 1.4G nitrate pentahydrate and 1.9 mL triethylamine. The mixture is heated until all dissolved and then slowly cooled to obtain crystals which are washed away andwith ethanol. After thorough drying they are ready for use. A frequently asked question is if this stuff is hot when in use. The answer is no, the crystals are not a chemical change, and therefore do not consume or release heat, but remain at a constant temperature. There may be some small heated by friction when they are broken, but it is not a crystal or a special property of triboluminescence.
