Preparation of cellulose-based fluorescent materials using Zinc sulphide quantum dot-decorated graphene by a one-step hydrothermal method

Abstract: Cellulose-based fluorescent materials using Zinc sulphide (ZnS) quantum dot-decorated graphene were prepared by a one-step hydrothermal method. X-ray photoelectron spectroscopy analysis identified the chemical states of Zn, S, C, O, and N in the composite paper. Transmission electron microscopy showed that the graphite oxide was reduced to graphene sheets, and ZnS nanoparticles (\10 nm) were deposited on the surface of these sheets. Scanning electron microscopy indicated that graphene sheets were attached to t… Show more

“…GOx is first obtained following the improved Hummers’ method and was further dispersed in HPDW. GOx is then decorated with ZnS:Mn QDs following a well-studied hydrothermal-assisted co-precipitation method used in similar graphene/QDs systems [ 46 , 47 , 48 ]. The surface morphology, particle size and particle abundance of the so-synthesized nanocomposite are depicted in Figure 1 .…”

“…A one‐step hydrothermal method developed by Bian and co‐workers allows the production of cellulose‐based fluorescence materials by loading ZnS quantum‐dot‐decorated graphene directly onto the surface of paper fibers (Figure ). The composite exhibits only a fewer defects and high fluorescence intensity.…”

“… 22 These ZnS QDs were immobilized onto the graphene surface using hydrothermal co-precipitation, exhibiting the strong fluorescence. 23 As ZnS(Mn) exhibits phosphorescence emission (~590 nm), the interference from biological tissues can be avoided as phosphorescence, making it an ideal candidate for biomedical applications. 24 , 25 , However, most of the QDs were immobilized on the graphene surface via hydrothermal assisted co-precipitation above 150 ° C resulting reduced graphene oxide (rGO), which is less favored over GO for biomedical applications due to higher water dispersibility and biocompatibility of GO.…”
