The optical Kerr effect exhibited by a nickel doped zinc oxide thin solid film was explored with femto- and pico-second pulses using the z-scan method. samples were prepared ultrasonic spray pyrolysis technique. Opposite signs for value of nonlinear refractive index observed in two experiments. Self-defocusing together two-photon absorption process 120 ps at 1064 nm, while dominantly self-focusing accompanied saturated found 80 fs 825 nm. Regarding nanostructured morphology resulting film,...
Measurements of the third-order nonlinear optical properties exhibited by a ZnO thin solid film deposited on SnO2 substrate are presented. The samples were prepared spray pyrolysis processing route. Scanning electron microscopy analysis and UV–Vis spectroscopy studies carried out. picosecond response at 1064 nm was explored z-scan technique. A large Kerr effect with two-photon absorption obtained. inhibition together noticeable enhancement in sample achieved incorporation Au nanoparticles...
Photoconduction and nonlinear optical refraction effects exhibited by an array of separated Au microchannels are reported. The samples were constituted thin solid films containing nanoparticles prepared evaporation method. photoconductivity the sample was measured with continuous illumination at 532 nm wavelength 1 W average power. A vectorial two-wave interaction allowed us to explore Kerr effect ns pulse duration. Z-scan experiments performed in a comparative film pointed out saturated...
In this Minding the Future column piece, a team from Mexico describe their efforts in moving data science program for high school and college students online during COVID-19 pandemic.The piece highlights both flexibility required of educators at height pandemic, to which many went ensure that educational opportunities continued, some cases even expanded.Statisticians scientists had-and continue have-a key role explaining abundance collected global as well clarifying what could (and not) tell us.
In this paper, we study photothermal effects in suspensions of gold nanorods water. The heating occurs owing to the light absorption and it is especially effective when frequency close localised surface plasmon resonance (LSPR). We use time-resolved Z-scan method monitor time-dependent temperature profile liquid under Gaussian beam illumination. Using experimentally measure parameters determine conditions for vapour generation different concentrations nanorods.
