Abstract: (1257 Views)
This paper reports the A simple and economical method to synthesize water soluble CdSe and CdSe: Gd QDs. The structural, luminescence and optical properties of these QDs were investigated by X-ray diffraction, Energy dispersive X-ray, optical absorption and photoluminescence spectroscopy measurements. XRD confirmed that CdSe and CdSe: Gd QDs had a cubic structure with good crystallinity. EDX analysis confirms the presence of Gd3+ in quantum dots. The as-prepared QDs exhibit good fluorescence properties. The presence of gadolinium ions in the crystal structure of quantum dots decrease the fluorescence Intensity of the quantum dots. But it can still be used in bio-imaging.
