چکیده
Photoluminescence (PL) of zinc sulfide powder synthesized and doped with Mn 2+ Eu 3+ ions by the method emerging reagents in a dodecane medium was investigated. In absorption excitation spectra PL samples ZnS : (Eu ), bands corresponding to transitions electrons from valence band conduction levels structural defects ZnS, as well transition 4f-electrons ground 7 F 0 excited electronic states were recorded. A wide associated recombination processes at energy on surface particles is observed spectra. Narrow are attributed 5 D -> j 4 T 1 6 ions. They intra-zone glow centers formed these structure. Energy transfer defect registered. Assumptions made about mutual influence alloying ions, synthesis conditions spectral properties substances. Keywords: non-aqueous synthesis, dodecane, sulfide, alloying, manganese (II) europium (III) photoluminescence.

Graphene demonstrated potential for practical applications owing to its excellent electronic and thermal properties. Typical graphene field-effect transistors and interconnects built on conventional SiO2/Si substrates reveal the breakdown current density on the order of 1 μA/ nm (i.e., 10 A/cm), which is ∼100× larger than the fundamental limit for the metals but still smaller than the maximum a...

The reaction dynamics of the boron monoxide radical (BO; XΣ) with diacetylene (C4H2; XΣg) were investigated at a nominal collision energy of 17.5 kJ mol−1 employing the crossed molecular beam technique and supported by ab initio and statistical (RRKM) calculations. The reaction is governed by indirect (complex forming) scattering dynamics with the boron monoxide radical adding with its boron at...

Inelastic neutron scattering on solid XeF2 and XeF2 targets was utilized to populate excited levels in 130Xe and 136Xe. When calculating nuclear matrix elements vital to the understanding of double-beta decay, it is important to have a clear understanding of the low-lying level structure of both the parent and daughter nucleus. Of particular relevance to double-beta decay searches are the assig...
