Single-step noninjection synthesis of highly luminescent water soluble Cu+ doped CdS quantum dots: application as bio-imaging agents.
Novel highly luminescent Cu(+) doped CdS quantum dots (QDs) were directly synthesized in aqueous phase through a facile single-step noninjection method. Due to their bright red fluorescence, ultrasmall size, and good biocompatibility, as-prepared CdS:Cu(+) QDs have potential as probes in bio-imaging.
متن کاملHigh-yield synthesis of graphene quantum dots with strong green photoluminescence
Recently, a kind of luminescent carbon nanomaterial – graphene quantum dots (GQDs) – has been attracting more and more attention. GQDs are graphene sheets of less than 100 nm in size, which have been regarded as a promising functional material due to their unique properties, such as ultraviolet and blue to green luminescence, two-photon induced FL, excellent photo stability, ands biocompatibili...
متن کاملMicrowave-assisted polyol synthesis of carbon nitride dots from folic acid for cell imaging
A green, one-step microwave-assisted polyol synthesis was employed to prepare blue luminescent carbon nitride dots (CNDs) using folic acid molecules as both carbon and nitrogen sources. The as-prepared CNDs had an average size of around 4.51 nm and could be well dispersed in water. Under excitation at 360 nm, the CNDs exhibited a strong blue luminescence and the quantum yield was estimated to b...
