| Popis: | The crystal structure of the mechanoluminescent complex [Sm(NO3)3(HMPA)3] (I) (HMPA – hexamethylphosphotriamide) has been determined. The studies of the luminescence properties in visible and near-IR ranges are presented. On the example of the triboluminophor I the model and the possible mechanism of formation of intrinsic mechanoluminescence were offered and the key role of the cleavage planes was revealed. The borders and width of the destruction zone are determined by the surfaces going through the neighboring central Sm atoms in the complexes where the key process – ionization of the charged NO3 – groups – proceeds under mechanical impact. |
