摘要: The optical limiting (OL) of detonation nanodiamond (DND) suspensions in engine oil was studied at a temperature range 20°C to 100°C. Oil were prepared on the basis DNDs with an average nanoparticle cluster size hydrosols (Daver) 50 and 110 nm. Raman spectroscopy used characterize samples. OL investigation carried out by z-scan technique. fundamental (1064 nm) second (532 nm) harmonic radiations YAG:Nd3+ laser passive Q-switching as excitation source used. thresholds for both 532 1064 nm determined. It is shown that decrease well increase wavelength incident radiation leads threshold increase. established performance not influenced increasing from results obtained show possibility using limiter wide range.
