Excitonic nonlinear absorption in CdS nanocrystals studied using Z-scan technique
J. He, W. Ji, G. H. Ma +5
Irradiance dependence of excitonic nonlinear absorption in Cadmium Sulfide (CdS) nanocrystals has been studied by using Z-scan method with nanosecond laser pulses. The wavelength d…

Ultrafast absorptive and refractive nonlinearities in multi-walled carbon nanotube film
H. I. Elim, W. Ji, G. H. Ma +3
By using femtosecond laser pulses at a wavelength range from 720 to 780 nm, we have observed absorptive and refractive nonlinearities in a film of multi-walled carbon nanotubes gro…
