“…[ 25 ] However, reports on the influence of (Ce, Dy) co‐doping on the structural and PL performance of the solution combustion synthesized ZnO nanoparticles are very limited, which led to the present investigation. Kalaiezhily et al [ 26 ] reported the tunable luminescence performance of combustion‐derived (Ce, Dy) co‐doped ZnO nanoparticles.…”

“…In this study, we synthesized ZnO nanoparticles using the solution combustion route and metal nitrates (host and dopant precursors) as oxidizers and urea as fuel. Unlike succinic acid used as an oxidizer in the synthesis process described by Kalaiezhily et al, [ 26 ] no additional oxidizer was used in the present study.…”

Solution combustion synthesized ZnO nanoparticles that were Ce doped, Dy doped or co-doped at varying dopant concentrations were characterized for their microstructural, optical, and photoluminescence (PL) characteristics. The synthesized nanoparticles matched the standard hexagonal wurtzite structure of ZnO. The lattice fringes in the high-resolution transmission electron micrographs and the bright spotty rings in the selected area electron diffraction patterns authenticated the high crystallinity of the nanoparticles. The diffuse reflectance spectroscopy resolved the energy bandgap for the undoped ZnO as 3.18 eV, which decreased upon doping and co-doping. A sharp narrow ultraviolet emission peak at $398 nm that originated from excitonic recombination was found in the PL spectra of the nanoparticles. The visible emission peaks in the PL spectra were assigned to the f-d and f-f electron transitions of Ce 3+ and Dy 3+ ions, respectively, in addition to different native defects in ZnO.The visible emissions (blue, yellow, and red) improved upon (Ce, Dy) co-doping, therefore (Ce, Dy) co-doped ZnO nanoparticles can be considered a promising luminescent material for the development of energy-saving light sources.

“…A number of lanthanide-doped ZnO materials, such as composites, films, nanoparticles etc., has already been reported in literature [7][8][9][11][12][13]. However, it's still unclear whether large number of lantanide ions can be dispersed in ZnO crystalline lattice or the ions can only segregate into crystalline lanthanide oxide due to large charge and radius of trivalent lanthanide ion.…”

A mixture of poly- and single crystals of zinc and ytterbium (2 at.%) oxides have been grown from the melt at high temperature (1430°C) and high pressure (3.8 GPa). The crystals were transparent under examination with naked eye. The diameter of crystals was in the range from 0.005 to 2 mm. X-ray diffraction confirmed presence of individual zinc and ytterbium oxides in the recovered samples. No change of zinc oxide lattice parameters was observed compared to pristine zinc oxide. Cathodoluminescence spectra of the mixture were recorded at 77 and 293 K. The collected spectra exhibit UV, green and near-infrared bands due to exciton recombination, presence of oxygen vacancies and ytterbium ions in ZnO crystals, respectively.
