AB  - Novel hybrid core shell structure with extensive absorption was synthesized by a two-step wet chemical route. Up-converting β-NaYF4:Yb,Tm core was obtained through EDTA assisted hydrothermal process, while the shell of anatase TiO2-Acetylacetonate charge transfer complex (TiO2-Acac) was formed over these via sol-gel method. Tetracycline was used to investigate photocatalytic efficiency of obtained structure under irradiation of reduced power Vis and NIR spectra. Owing to the fact that 1D2→3F4 and 1G4→3H6 emission of Tm3+ matches well with the absorption edge of TiO2-Acac, radiation-reabsorption and FRET processes improve the overall generation of reactive oxygen species and degradation of tetracycline. Beside it, formation of tetracycline intermediates immediately after the addition of this novel hybrid core-shell structures, making them a promising material for water purification through the synergy of catalytic and photocatalytic processes.

AB  - Up-converting nanoparticles (UCNPs) have unique optical properties to convert NIR to VIS light, and therefore are widely used in optoelectronics, forensic, medicine, etc. [1,2]. During the last decade interest in obtaining of the pure hexagonal (β) NaYF4:Yb/Er phase through some environmental friendly method which could be easily scaled-up is permanently present in scientific community. Different synthesis methods, like co-precipitation, thermal decomposition, hydro- and solvo-thermal methods were usually reported like promising ones, but obtaining of the highly efficient (β) phase is usually coupled with harsh processing conditions [3]. This phase is characterized by a higher degree of crystal asymmetry and multisite dopant accommodation which ensures better luminescence response than of cubic (beta) phase. To prevent nucleation of kinetically stable alpha phase, we applied for the first time ultrasound treatment (20 kHz, Vibra Cell VCX750 Sonic) to the simple mixture of the rare earth nitrates and NaF in different solvents (ethanol and water) for 30, 60, 90 and 120 min.

AB  - Up-conversion is the optical property of materials which have ability to convert low energy photons (usually from infrared spectrum) into higher energy photons (from visible spectrum). Such compounds, usually lanthanide doped oxides or fluorides, have many applications in photoluminescence science and technology today. Currently, (β) NaYF4:Yb,Er polymorph is considered to be the most efficient up-converting material. Its synthesis usually includes the usage of toxic solvents, long-term heating, high pressures, controlled gas atmosphere, etc. The aim of this work was to utilize rarely applied sonochemical synthesis for the stabilization of (β) NaYF4:Yb,Er phase under mild and environmental friendly conditions. For this purpose, we performed ultrasonic treatment of common nitrate precursors and sodium fluorine for a different time. The obtained powders were analyzed in order to determine their phase composition and thermal stability, morphology, dopants distribution, particles surface purity and luminescent characteristics. Owing to this, the chemical and crystal phase transformations that occurred  in specified periods of synthesis time are explained in detail. Moreover, it was shown that obtaining of uniformly doped (β) NaYF4:Yb,Er mosocrystalline particles is possible after 2h of sonication.

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.
