“…Triboluminophores are a rather wide class of organic and inorganic substances in a crystalline form. The nature of this physical phenomenon is not quite clear [21]. As a rule, the spectrum of triboluminescence nearly or completely coincides with the spectrum of photoluminescence [22].…”

“…Recently, the interest in new materials capable of triboluminescence has increased due to the creation of lightemitting sensors of destruction [21,22]. The discovery of triboluminescence in composite organosilicon materials of which the spicules of hexactinellid sponges are built may contribute to the creation of biomimetic materials capable of generating light emission.…”

The morphology, chemical composition, and optical properties of long monoaxonic spicules were studied in several species of marine deep-sea hexactinellid sponges of different orders and families: Asconema setubalense (Hexasterophora, Lyssacinosida) and Monorhaphis chuni Schulze (Monorhaphiidae). Their macrostructural organization is a system of thin layers laid around the central cylinder containing a square canal filled with organic matter. A significant role in spicule organization is played by the organic matrix. The macrostructural of organization of the spicule in Monorhaphis chuni is a system of the "cylinder-within-a-cylinder" type. However the spicule surface is covered with ridges. They penetrate a few layers into the spicule. Analysis of the elemental composition of the basalia spicule of Monorhaphis chuni demonstrates a heterogeneous allocation of C, O, Si on the spicule surface, subsurface layers, and on ridges. All studied spicules have the properties of anisotropic crystals and they demonstrate a capability to the birefrigence. On the other hand we discovered unique property of spicules-their capacity for triboluminescence. The discovery of triboluminescence in composite organosilicon materials of which the spicules of hexactinellid sponges are built may contribute to the creation of biomimetic materials capable of generating light emission.

“…Building upon the widely cited method by Greenham and de Mello, new instrumentation and updated methods allow a range of sample types to be measured and the effects of re-absorption addressed [31][32][33][34][35]. Note that the same precautions used for solutions regarding sample purity and control experiments have to be taken to ensure reliable data.…”

Abstract: Guidelines for measuring the luminescence of inorganic compounds, metal complexes, and organometallic compounds are described. Common textbooks and manuals describing luminescence measurements are usually targeted for organic compounds, and are not always suitable for inorganic and organometallic compounds, which emit room-temperature phosphorescence. The report describes problems that researchers may confront while recording emission data and elaborates clear procedures to avoid these problems and provide adequate standardized protocols.

“…Bourhill et al [66] used the photoluminescence (PL) quantum yield as a measure of the TL efficiency of different TL materials (Table 2) based on the assumption that both phenomena originate from the same excited state for the compounds studied. ZnS-Mn has the highest triboluminescent efficiency among the TL materials investigated.…”

“…Metal complexes are among the most intense TL materials known [28]. Metal complexes include europium tetrakis (dibenzoylmethide) triethylammonium [64], tris (1,3-di-tert-butyl-B-propane dione) terbium-p-dimethylamino pyridine [66] and dibromobis (triphenylphosphine oxide) manganese [42,67]. Most metal complexes contain a trivalent lanthanide as the emitting center [28].…”
