Scalable and economical synthesis of fluorescent graphene quantum dots using graphene oxide as precursor material is presented in this report. Graphene oxide was coated in bottom of double-necked round bottom quartz flask. One neck connected to a controlled hot air blower and other was connected to condenser which was connected to vacuum pump. The flask was heated at high temperature, hot air was passed in and vacuum pump was switch on. Graphene quantum dots were deposited on the walls of condenser which was dissolved out through acetone. Size and morphology were observed using transmission electron microscope and scanning electron microscope. Fourier transformation infrared spectroscopy indicated presence of oxygen containing groups which were responsible for fluorescence. Fluorescence of as synthesized materials was also recorded, presence of strong luminescence peaks at 375 nm, 391 nm and 516 nm. Fluorescence behavior of GQDs was applied for bioimaging of A-549 cancer cell-lines.
