Transparent amorphous zinc oxide thin films for NLO applications

Nonlinear optical properties of zinc oxide doped bismuth thin films using Z-scan technique

“…The calculated values of the nonlinear absorption coefficient (b) and the third-order nonlinear optical susceptibility for each sample are collected in Table 1 as follows, the obtained results are similar to other works in the literature [25,26]:…”

Linear and nonlinear optical properties of ZnO thin films deposited by pulsed laser deposition

“…As a source a pulse nitrogen laser was used (λ = 337.1 nm, FWHM = 5 ns, power in pulse 20 kW, 10 Hz repetition rate). Photoluminescence (PL) signal was registered using photomultiplier (HAMAMATSU R928) and the boxcar averager (162/164 PAR) [15]. All photoluminescence measurements were carried out for samples placed into a vacuum chamber with pressure equal about 10 -2 Pa.…”

“…The time-resolved signals were integrated at the peak photoluminescence energy equal to 3.35eV for the time-resolved photoluminescence measurements presented in Figs.7a-b. All measurements of the TRPL process was carried out within temperature range from 13K to 300K using nitrogen pulsed laser and real-time multichannel scaller (RTMS) [6,[11][12]15]. This experimental setup allows capturing TRPL in real time after every laser pulse.…”

Optical properties of MgO thin films grown by laser ablation technique

“…Nitrogen laser (k = 337.1 nm, FWHM = 5 ns, power in pulse 20 kW and 10 Hz repetition rate) was used as excitation source. Photoluminescence signal was registered by using photomultiplier (HAMAMATSU R928) and the boxcar averager (162/164 PAR) (Zawadzka et al 2014b). Measurements of the PL process were performed within temperature range from 13 to 300 K. Samples were placed in vacuum chamber and cooled to temperature equal to 13 K. Experimental spectra were registered after 30 min from reaching desirable temperature.…”
