I am trying to synthetize GQDs from graphene oxide, that emits on the green, however the final PL analysis showed emission on diferent wavelengths.

Can anyone tell me how I can purifie the sample or suggest a synthesis methodology for have just emission at green region?

How to know the space group of a powder if we only have a XRD pattern of a material and also its not getting matched with any of the standard XRD ?

What's the way out of this problem? Can the single-crystal technique do this task? If yes, What if we also can't make a single crystal of this powder material?

But I need an method for large scale synthesis of short-SWCNTs. I belive that with those approaches is difficult.

Ioannis Samaras

Dear Gil Goncalves,

proposal processes for medium to large scale synthesis - of (commercial) _wCNTs- maybe : 1)electron beam irradiation[1] and 2)powder ball milling[2].
