Enhanced quantum efficiency for Dy super(3+) Emissions in water dispersible PbF sub(2) nanocrystals

Enhanced quantum efficiency for Dy super(3+) Emissions in water dispersible PbF sub(2) nanocrystals

PbF sub(2) nanocrystals found to be a better host for Dy super(3+) ions to exhibit better quantum efficiency. The optimum dopant concentration is found to be higher than that observed in several bulk materials. The nanocrystals are rendered water dispersible by coating poly(acrylic acid) over their...

Zusammenfassung:PbF sub(2) nanocrystals found to be a better host for Dy super(3+) ions to exhibit better quantum efficiency. The optimum dopant concentration is found to be higher than that observed in several bulk materials. The nanocrystals are rendered water dispersible by coating poly(acrylic acid) over their surface.
