Nanodiamonds (NDs) and carbon-dots (CDs) suspensions exhibit significant NLO response under both ps and ns laser excitation. NDs exhibit important optical limiting action under nanosecond visible (532 nm) and infrared (1064 nm) laser excitation.
A new organic nonlinear optical material, imidazolium diphenylacetate diphenylacetic acid, with excellent structural characterization and nonlinear optical activity has been reported.
Rare-earth n-tuple decker phthalocyanine complexes exhibit superior optical limiting properties than the neutral double-decker derivatives, with the normalized transmittance reduced to about 80%.
Third-order nonlinear optical response and optical limiting of colloidal carbon dots
