Lead-flux Growth of Eu4Ir8As7 Crystals
Single crystals of the new arsenide Eu4Ir8As7 were grown from a lead flux. The structure was refined on the basis of single-crystal X-ray diffractometer data: Ca4Ir8P7 type, P21/m, a = 1311.3(1), b = 408.4(1), c = 1360.3(1) pm, β = 98.45(1)◦, wR2 = 0.0640, 1985 F2 values, 95 variables. The iridium and arsenic atoms in the Eu4Ir8As7 structure build up a complex three-dimensional, covalently bond...
متن کاملEffect of impurities on the optical properties of KTP single crystals grown from flux
In the present work, KTP crystals have been grown by spontaneous nucleation technique in flux medium using K6P4O13 flux. 0.4-1 °C/h cooling rates were applied in the spontaneous nucleation process. The presence and amount of impurities has been determined by using XRF. The optical transmission spectra of impure KTP crystals in the UV–visible region are discussed. The transmission cut-off is cle...

متن کاملBismuth Flux Growth of CeRh6Ge4 and CeRh2Ge2 Single Crystals
Single crystals of the germanides CeRh6Ge4 and CeRh2Ge2 were synthesized from the elements in bismuth fluxes. Polycrystalline samples are available by arc-melting. The structures were refined on the basis of single-crystal X-ray diffractometer data. CeRh6Ge4: LiCo6P4 type, P6m2, a = 715.4(2), c = 385.5(1) pm, wR2 = 0.0554, 273 F2 values, 19 variables; CeRh2Ge2: ThCr2Si2 type, I4/mmm, a = 415.69...
متن کاملHydrothermal synthesis of NiWO4 crystals for high performance non-enzymatic glucose biosensors
A facile hydrothermal route for the synthesis of ordered NiWO4 nanocrystals, which show promising applications as high performance non-enzymatic glucose sensor is reported. The NiWO4-modified electrodes showed excellent sensitivity (269.6 μA mM(-1 )cm(-2)) and low detection limit (0.18 μM) for detection of glucose with desirable selectivity, stability, and tolerance to interference, rendering t...
