Concentration-dependent optical properties of erbium doped zirconia nanocrystals

چکیده
This study has investigated the effect of dopant concentration on the luminescent emission of Er in ZrO2 nanocrystals. The structure and morphology of the resulting nanocrystals were characterized by X-ray diffraction and field emission scanning electron microscope. The room-temperature optical properties of synthesized nanocrystals were studied by photoluminescence spectroscopy. The dependence of the luminescence emission on the doping concentration was examined to determine the optimum Er 3+ concentration in the samples. Strong luminescence quenching was also observed in samples with high Er 3+ concentrations in the ZrO2 host lattice. The luminescent erbium doped zirconia nanocrystals are promising for applications such as fluorescent biomarkers, optical display systems, lamps, etc.

Co2+ & Er3+ co-doped ZnO nanocrystals were synthesized by the hydrothermal method at 180°C and pH= 12 for 48 h. Powder XRD patterns indicate that the Zn1-2xErxCoxO crystals (0.00<x≤0.035) are isostructural with ZnO. The cell parameters increase for Er3+ and Co2+ upon increasing the dopant content (x). SEM images show that doping of Er3+ and Co2+ into the sites of Zn2+ does not change the morpho...
