Through the phenomenon of cavitation were developed synthesis for carbon
quantum dots (CQD) and quantum dots of carbon doped (N-CQD). We used as
precursor glucose, CQD was used a route acid (HCl) and other basic (NaOH), the
dopier for the N-CQD was NH3. This paper makes a comparison between the
techniques of ultrasonic and ultrasonic probe with the purpose of finding short
times to obtain the CQD and N-CQD. The characterization of photoluminescent
properties of the nanoparticles were realized by fluorescent
spectrophotometry, UV-Vis spectroscopy and microscopy electron scanning
(SEM). The literature review reported obtaining this type of particles with sonic
process 2: 00 to 4: 00 in the case of the ultrasonic and 1: 00 to 2: 00, in the case
of the probe. In this paper the times have been reduced at least 50% and we
have obtained nanoparticles with quantum efficiency similar to those reported.
Likewise, is has observed that the effect of autolumisniscence favored the
intensity of the nanoparticles.
