For the first time the Z-scan measurements and second harmonic generation of δ-BiB3O6:Pr3+ large-size nanocrystallites embedded into the polyvinyl alcohol (PVA) polymer matrices and deposited on AlZnO substrates decorated with Ag NP were studied. The comparison of the second and third order NLO is presented. The Z-scan measurements were done by 5ns Nd:YAG laser and the second harmonic generation was measured using the 25ns Nd:YAG laser with frequency repetition about 10Hz. The measurements have shown that both second as well as third-order susceptibilities are sensitive to the sizes of the Ag NP deposited on the AlZnO substrate. The obtained results confirm a principal role of the Ag NP on the output nonlinear optical properties which may be a consequence of the contribution of the low-dimensional nano-trapping levels. •Complex polymer silver BiB3O6 nanocomposites are synthesized.•Z-scan and second harmonic generation show existence of some maximum at 20nm sizes.•Principal role of surface plasmon resonances interacting with the localized states is shown.
