AB  - Ca1-xGdxMnO3 (x = 0.05–0.20) nanostructured perovskites were successfully synthesized by modified glycine nitrate procedure (MGNP). Temperature intervals of sintering and phase transition during heating were revealed during dilatometric measurements. In order to determine the band gap values of the tested samples, ellipsometric measurements were performed in the UV-VIS spectral range. Decrease of band gap values with increase of Gd dopant content was attributed to n-type doping and upward shifting of the Fermi level in the conduction band. The investigation of the crystal structure and phase content of nanocrystalline Ca1- xGdxMnO3 powders was continued using micro-Raman spectroscopy. The electrical conductivity of Gd3+ doped sintered samples CaMnO3 as a function of temperature was measured by electrochemical impedance spectroscopy (EIS), in the temperature range of 400–700 °C. The corresponding activation energies of conductivity, measured in the investigated temperature range, were also discussed. The obtained research results showed that the highest hardness values of 7.58 GPa respectively, were achieved and that these nanostructured materials can be used as a high-density ceramic material for various industrial applications.

AB  - The Nonlinear Laser Scanning Microscopy (NLSM) contributes to the cell labeling through addressing two main issues: photobleaching and phototoxicity. Moreover, an increase of the penetration depth and a reduction of background autofluorescence are achieved.We have used a multidisciplinary approach combining expertise in material science, nanoparticles synthesis and characterization, cancer cell and tissue labeling, and high resolution imaging, in order to accomplish in vitro imaging of the cancer cells. We have imaged the oral squamous carcinoma cells and human gingival cells. We have demonstrated that we are able to take high contrast images. We have shown position of the nanoparticles in cells, through colocalization of the cell auto-fluorescence and the nanoparticles up-conversion.We plan to improve our abilities through further optimization of the up-converting nanoparticles (smaller and brighter particles) and microscopy technique.

AB  - Synthesis of monosized and spherical Up-Converting NanoParticles (UCNPs) with biocompatible surface are of a great interest because of their potential application in biomedicine as biomarkers or drug delivery systems. Among different synthesis routes reported in the literature, a hydro/solvo thermal method is consider to be most potential one for scaling-up due fact that is simple and economically cost-effective. In this work the synthesis of NaY0.65Gd0.15F4:Yb,Er UCNPs were performed through chitosan assistant solvothermal synthesis at 200oC. Variation of precursors concentration, type of solvent and synthesis time were performed in order to explore their influence on the structural, morphological and optical properties of the UCNPs. The XRD analysis showed that with a smaller surplus of fluoride ions the formation of Y0.65Gd0.15F4:Yb,Er orthorhombic phase occurs, while the increase of fluoride content or reaction time leads to NaY0.65Gd0.15F4:Yb,Er cubic phase formation. Along with it, the changes of UCNPs morphology from spindle to spherical shape is detected. All samples emitintense green emission due to the (2H11/2, 4S3/2) → 4I15/2electronic transitions, after been excited with infrared light (λ=978 nm).

AB  - Up-converting nanoparticles (UCNPs) with unique ability to convert NIR to VIS light (anti-Stokes process) have a wide application in optoelectronics, forensic, security labeling and biomedicine. Over the past few years different methods (like co-precipitation, thermal decomposition, hydro/solvothermal synthesis, etc.) are used for synthesis of β-NaYF4: Yb/Er phase, mainly from toxic organic precursors. In this work we explore conditions for stabilization of β-NaYF4: Yb/Er phase in nanoparticles applying sonochemistry synthesis of common inorganic precursor. The XRPD analysis showed that pure β phase is possible to obtained after 120 min of ultrasonification, while for shorter processing time (30-90min), cubic α-NaYF4: Yb/Er or orthorhombic YF3 : Yb,Er phase were founded too. The SEM and TEM analysis reveal presence of elongated nanoparticles self-assembled in spindles long up to 500 nm. Evolution of particle morphological and particle composition are analysed and correlated further with intensity of green emission (2H11/2,4S3/2→4I15/2) intensity measured under excitation of 978 nm.
