In the present investigation, Fe doped and glucose capped zinc oxide (ZnO) quantum dots (QDs) were prepared by using simple green synthesis method under room temperature as it is an environmental friendly process. Then their structural and optical properties were examined by using X-ray diffraction (XRD), Transmission electron microscope (TEM), Ultraviolet (UV) and Photoluminescence (PL) techniques. During this study period, an interesting cubic-hexagonal crystal nature was confirmed through powder XRD technique and also a spherical shaped surface morphology was found from TEM images whose size is approximately 10 nm. The UV results have shown an enhanced absorption when compared with uncapped ZnO:Fe QDs. Further, an interesting strong blue emission was observed in the glucose capped ZnO:Fe QDs which was maximum at 465 nm because of formation of small size particles and broad emission band was also observed from violet to red region. This enhanced emission nature is highly suitable for all types of bio-applications. The results of the present study show the glucose capped ZnO:Fe QDs induced a better antibacterial activity when compare other QDs. In future, these QDs can be used for cancer cell targeting application.
