Characterizations of crystalline nanoparticles and nanorods. TEM images: (a) nanoparticle (CISNP1), (b) nanoparticle (CISNP2), (c) nanorod and length nm (CISNR), (d) UV-Vis absorption and fluorescence (excited at 300 nm) spectra, and (e) XRD patterns with wurtzite and zinc blende phases.
Open-aperture Z-scan curves of (a) CISNP1 (6.5-nm diameter), (b) CISNP2 (12.5-nm diameter), and (c) CISNR ( nanorods).
(a) One-photon-excited TA signal of CISNP2 [Pump (390 nm)-Probe (780 nm)], (b) pump-power dependent at zero delay time, (c) two-photon-excited TA signal of CISNP2 [Pump (780 nm)-Probe (780 nm)], and (d) pump-power dependent at zero delay time.
TPA coefficient, TPA cross-section, nonlinear refractive index, and exciton decay times [one-photon (390 nm pump) and two-photon (780 nm pump) excitation] of crystalline nanoparticles and nanorods.
