Carbon-based materials have been a great scientific interest in recent decades due to the abundant availability and wide variety of electronic
mechanical and physicochemical properties
which gives these materials an extensive applicability. Among these fields is the nano-scientist
in which materials at nano scale present unique and interesting properties. 20 nm present luminescent properties similar to semiconductor quantum dots (QDs)
but these have the particularity that carbon-based nanostructures are mostly low or nonexistent toxics. These materials focus their use in biological and environmental applications such as biomedical studies
fluorescent markers for the cellular imaging
drug tracking
clinical diagnosis and markers or detectors of contaminants in aquifer systems. This work proposes a methodology for the synthesis of fluorescent boron-doped carbon nanostructures (BCND's) with emission maxima in the range 420-520 nm from graphene oxide by a microwave-assisted hydrothermal treatment. The characterization was performed by spectroscopic techniques: UV-VIS
RAMAN
FTIR-ATR
steady-state fluorescence and Scanning Electron Microscopy (SEM).
