Journal ArticleDOI
Towards broad range and highly efficient down-conversion of solar spectrum by Er3+–Yb3+ co-doped nano-structured glass-ceramics
TL;DR: In this article, the authors show new down-conversion mechanisms in Er3+−Yb3+ co-doped glass-ceramics, where the ions are hosted by fluoride nanoparticles embedded in silica glass.
Journal ArticleDOI
Nanocrystal-size selective spectroscopy in SnO2:Eu3+ semiconductor quantum dots
TL;DR: In this article, a fraction of the Eu3+ ions were incorporated to the SnO2 nanocrystals in the process of thermal treatment of sol-gel glasses, and it was possible to excite selectively Eu 3+ ions located in SnO 2 nanocrysts, by energy transfer from the host, obtaining emission spectra that depend on the nanocrystal size.
Journal ArticleDOI
Cooperative energy transfer in Yb3+–Tb3+ codoped silica sol-gel glasses
TL;DR: In this article, the temporal evolution of the blue-green upconversion emissions coming from Tb3+ ions and their dependence on the excitation intensity at about 1 μm has been studied.
Journal ArticleDOI
Luminescent properties of transparent nanostructured Eu3+ doped SnO2?SiO2 glass-ceramics prepared by the sol?gel method
TL;DR: The mean radius of the obtained SnO2 nanocrystals, ranging from 2 to 5 nm, is comparable to the exciton Bohr radius, corresponding to wide bandgap semiconductor quantum dots in an insulator SiO2 glass as discussed by the authors.
Journal ArticleDOI
Luminescence and structural characterization of transparent nanostructured Eu3+-doped LaF3–SiO2 glass–ceramics prepared by sol–gel method
TL;DR: In this article, the fraction of Eu 3+ ions partitioned into LaF 3 nanocrystals, substituting La 3+ ion, is comparable to the one staying in the SiO 2 glassy phase.
