Making Graphene Quantum Dots

Synthesis of graphene quantum dots from citric acid and urea. I fully intend to make this into a full series.

Materials: Citric acid, urea, UV source

Hazards: None

Method: "Controlled synthesis of blue luminescent graphene quantum dots from carbonized citric acid: Assessment of methodology, stability, and fluorescence in an aqueous environment" (Materials chemistry and Physics Journal Volume 220)

really cool, well spoken and neat, i had never considered how they were made but neat to know. Thanks! and keep up the great work, excited to see what comes next! :)

[PiyushChoudharyPPH]

Tried it just now. It really worked!!!

During my master thesis I prepared by thermal degradation of citric acid and ammonium acetate. Purification by dialysis. Usually gqd emission is excitation dependent, color change with excitation

Other than drying and sieving the dots to get the correct size, the only other way I can think of that you could do at home would be with a centrifuge.

Just found your channel.. Great stuff.. Keep going

It would be better if you draw the reaction first on the board and then perform the experiment

Please do a video on how to get carbon quantum dot powder.

[oitthegroit]

What music did you use? It goes perfectly with the video.

Who is here after the nobel announcement.

[muntahamahin]

Which type of syringe filter did you use can you tell me?what’s the pore size?

[davidljdavidlj]

The brown color makes me think you made graphine oxide.

moonlight sonata second movement? strange background music for the topic and narration.

Hello.. can u please help me for graphene quantum dots synthesis for breast cancer treatment as a sensor

[AdricM]

amazing im gonna see about replicating!

[bacchemankesacche]

how to check the size of as synthesized quantum dots

[ronin]

I wonder how more abused the word 'quantum' can get.

[Drjtherrien]

My PhD thesis was about silicon nanoparticles we made using electrochemical etching. I had to use a HPLC system to separate the particles by size. I would imagine this could work here too.

"Inorganic synthesis"
Citric acid seems organic to me...

[bacchemankesacche]

i checked by DLS it is not giving the single peak and also avg size more than 400nm
