Y0.8−xGdxF3:Yb/Er mesocrystals with a biocompatible surface and diverse morphological
characteristics were successfully synthesized using chitosan-assisted solvothermal processing. Their
structural properties, studied using X-ray powder diffraction, Fourier transform infrared spectroscopy,
scanning and transmission electron microscopy and energy di...
Mechanically activated strontium titanate (SrTiO3) powders with various iron (III)oxide (Fe2O3) doping levels (1.5, 3, and 6 wt%) were prepared by solid state method. Due to the possibility of iron ion incorporation in SrTiO3 onto Sr2+ and/or Ti4+ sites a detailed analysis of the influence of dopants on the microstructure, morphology, optical prope...

Hydroxyapatite attracts great attention as hard tissues implant material for bones and teeth. Its application in reconstructive medicine depends on its biocompatibility, which is in a function of composition and surface properties. The insertion of a protein element in the composition of implants can improve the cell adhesion and the osseointegrati...
Nanopowders of up-conversion SrGd2O4 orthorhombic (Pnma) phase co-doped with different Yb³⁺ (1, 2.5 and 5 at%) and constant Er³⁺ (0.5 at%) ions were successfully prepared via sol-gel assisted combustion. Rietveld refinement indicated unit cell lattice parameters increase with Yb³⁺ and Er³⁺ ions doping. Scanning transmission electron microscopy with...
In this paper, we report the mild sonochemical synthesis of hexagonal (β) NaYF4:Yb,Er mesocrystals at low temperature of 40 °C. The nucleation and transformation of crystal structures is investigated in the course of time, and it is shown that the pure β phase is obtained after 2 h of pulsed sonication. The crystallization of orthorhombic YF3:Yb,Er...
Up-converting \(\hbox {NaYF}_{4}\):Yb,Er nanoparticles were obtained by polymer-assisted solvothermal synthesis using a common solution of hydrated RE nitrates in ethanol or ethylene glycol. It was shown that polymer choice (polyacrylic acid—PAA, polyvinylpyrrolidone—PVP and chitosan—CS) controls the size and shape of \(\hbox {NaYF}_{4}\):Yb,Er nan...
The synthesis of lanthanide doped up-converting nanoparticles (UCNPs), whose morphological, structural, and luminescence properties are well suited for applications in optoelectronics, forensics, security, or biomedicine, is of tremendous significance. The most commonly used synthesis method comprises decomposition of organometallic compounds in an...
Single phase β‐NaY0.8‐xGdxYb0.18Er0.02F4 nanoparticles with different concentrations of gadolinium ions were prepared via PVP‐assisted solvothermal treating at 200°C (PVP‐ polyvinylpyrrolidone). With the increase in Gd³⁺ concentration, size of the nanoparticles decreased. The up‐converting spectra recorded upon 980 nm irradiation showed the green (...
The emerging up-conversion nanoparticles (UCNPs) offer a wide range of biotechnology applications, from biomarkers and deep tissue imaging, to single molecule tracking and drug delivery. Their successful conjugation to biocompatible agents is crucial for specific molecules recognition and usually requires multiple steps which may lead to low reprod...
Lanthanide-doped fluoride up-converting nanoparticles (UCNPs) represent the new class of imaging contrast agents which hold great potential for overcoming existing problems associated with traditionally used dyes, proteins and quantum dots. In this study, a new kind of hybrid NaYF4:Yb,Er/PLGA nanoparticles for efficient biolabeling were prepared th...
In this feature article, we highlight our works on compositional and structural dependence of up-converting rare earth (RE) fluorides obtained through ethylenediamine tetraacetic acid (EDTA) assisted hydrothermal synthesis. Various nanostructures were obtained by tuning of experimental conditions, such as precursor’s concentration, degree of doping...
Fluorescent nanoparticles have an important role in biological analyzes, and in the last ten years they are successfully applied in a visualization and characterization of biological processes at the cellular and molecular level, as well as, in the development of fluorescent lamps, displays, plasma screens and protective labels. The great interest...
Owing to their unique optical properties, up-converting rare earth fluorides have attracted extensive attention in recent years. Varieties of synthesis procedures which generate nano- and micro-crystals with controllable compositions have been reported. In the vast majority, surfactants, complexing agents and solvents play essential role in control...
