چکیده
The anti-Stokes photoluminescence (PL) of perovskite CsPbBr 3 nanocrystals in a fluorophosphate glass matrix has been found and experimentally studied upon optical excitation to the low-energy edge band. intensity PL depends linearly on pumping power increases rapidly with increasing temperature. A simple three-level model is proposed that describes well main regularities observed phenomenon. Keywords: perovskites, nanocrystals, photoluminescence, , glass.

15 صفحه اولEmerging Photoluminescence in Monolayer MoS<sub>2</sub>
Novel physical phenomena can emerge in low-dimensional nanomaterials. Bulk MoS2, a prototypical metal dichalcogenide, is an indirect bandgap semiconductor with negligible photoluminescence. When the MoS2 crystal is thinned to monolayer, however, a strong photoluminescence emerges, indicating an indirect to direct bandgap transition in this d-electron system. This observation shows that quantum ...

Two new rare-earth dicyanamides, namely, Tb[N(CN)2]3‚2H2O and Eu[N(CN)2]3‚2H2O, have been prepared by ion exchange in aqueous solution, followed by evaporation of the solvent at room temperature. The structures of both compounds have been solved and refined from single-crystal and powder X-ray diffraction data, respectively. The two compounds are isostructural and are built up from irregular qu...
