Abstract
A method of synthesizing carbon quantum dots (CQDs) includes using a dried ground Halodule uninervis seagrass to form a suspension in water, followed by centrifuging and filtering through a filter membrane and a dialysis membrane to form a CQDs solution. The CQDs have a Stokes shift of less than 83.0 nm at an excitation wavelength of 380 to 430 nm.
Claims15
A method of synthesizing carbon quantum dots (CQDs), comprising:
- grinding a dry Halodule uninervis seagrass to form a seagrass powder;
- heating a mixture comprising water and the seagrass powder to form a suspension;
- centrifuging the suspension to obtain a supernatant;
- filtering the supernatant through a filter membrane and a dialysis membrane to form a CQDs solution comprising a plurality of CQDs,
- wherein the carbon quantum dots have a Stokes shift of less than 83.0 nm at an excitation wavelength of 380 to 430 nm.
