Multicolor tuning of lanthanide-doped nanoparticles by single wavelength excitation.
Lanthanide-doped nanoparticles exhibit unique luminescent properties, including large Stokes shift, sharp emission bandwidth, high resistance to optical blinking, and photobleaching, as well as the unique ability to convert long-wavelength stimulation into short-wavelength emission. These attributes are particularly needed for developing luminescent labels as alternatives to organic fluorophore...
متن کاملNitrogen-doped carbon dots with excitation-independent long-wavelength emission produced by a room-temperature reaction.
Nitrogen-doped carbon dots (CDs) have been produced by a new facile "bottom-up" synthesis, using the room-temperature reaction between acetonitrile and sodium-naphthalene. The obtained hydrophobic CDs are monodisperse (∼2.6 nm) and present an excitation-independent emission at ∼588 nm with a small full width at half-maximum (FWHM) of ∼52 nm. The CDs can be simply modified to be hydrosoluble and...
متن کاملMechanically induced self-propagating reaction of vanadium carbonitride
Vanadium carbonitrides (VCxN1-x) were prepared via mechanosynthesis from mixtures of elemental vanadium and carbon with different V/C atomic ratios under a nitrogen atmosphere using a high-energy ball mill. We obtained the full composition range of carbonitrides at room temperature. The products were characterized using X-ray diffraction, scanning electron microscopy and electron energy loss sp...
متن کاملSystematic Tuning of the Luminescent Properties of Self-Activated ZnGa2O4 Phosphors by Cd Ion Substitution
The e4ect of host compositions on the luminescent properties of spinel-type ZnGa2O4 phosphors was investigated by systematic substitution of Cd for Zn in the host lattice. A continuous solid solution with the composition (Zn12xCdx)Ga2O4 (04x41.0) was synthesized at 9503C as self-activated phosphors, as indicated by X-ray di4raction (XRD) analysis. With increasing substitution of Cd the emission...
