Abstract
This study has investigated the effect of dopant concentration on the luminescent emission of Er3+ 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 Er3+ concentration in the samples. Strong luminescence quenching was also observed in samples with high Er3+ 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.
