As one of the most active areas in laser protection, organic/inorganic hybrid functional materials have been expected to play an extremely important role in the field of optical limiting. The optical limiting performance of the CH 3 NH 3 PbI 3 perovskite:poly(N-vinylcarbazole) (weight ratio: 1 : 1) blends (hereafter abbreviated as CP) was experimentally studied in DMF and in a poly(methylmethlacrylate) (PMMA) matrix, respectively, using an open aperture Z-scan method. In contrast to the CP dispersed in DMF, which showed no apparent nonlinear optical (NLO) response at both 532 and 1064 nm, after annealing at 200 C in N 2 for 30 min, a saturable absorption (SA) response was observed in the same DMF dispersion under the excitation of 532 nm laser. At 1064 nm, the annealed sample displayed different NLO responses: SA at the lower pulse energy and reverse saturable absorption (RSA) at the higher pulse energy. Both the 3 wt% and 6 wt% CP-doped PMMA composite films exhibited a typical RSA response, larger nonlinear absorption coefficient and superior optical limiting performance when compared to the same blends in DMF dispersion.In the past decades, signicant research effort has been invested in state-of-the-art optical limiting (OL) materials (e.g. fullerenes, carbon nanotubes, polymer/nanotube composites, porphyrins, phthalocyanines, mixed metal complexes, carbon black suspensions, two dimensional nanosheets, nanowires, nanobers and nanoparticles as well) in an attempt to achieve some measure of protection from laser beams. 1-5 A large number of essential strategies have been employed to control and optimize the OL characteristics of nonlinear optical (NLO) materials for practical laser protection. However, the preparation of novel nonlinear and optically active materials with excellent thermal stability, small limiting threshold value, large laser damage threshold value, ps/ns response time and broadband spectral range, still presents a signicant challenge.Since 2009, organometal halide perovskites (e.g. CH 3 NH 3 -MX 3 (M ¼ Pb, Sn; X ¼ Cl, Br, I), CH 3 NH 3 MBr x X (3Àx) (M ¼ Pb, Sn; X ¼ Cl, I), (C 4 H 9 NH 3 ) 2 (CH 3 NH 3 ) (xÀ1) Sn x I (3x+1) , CH 3 NH 3 PbCl x -I (3Àx) and others) have attracted signicant attention worldwide, 6-9 especially in organic photovoltaics (including dyesensitized solar cells and other organic solar cells), due to their high electron mobility (66-2300 cm 2 V À1 s À1 ), 10 long exciton diffusion length (100-1000 nm), 11,12 high linear absorption coefficient (1.5 Â 10 4 cm À1 at 550 nm), 13 tunable bandgap (1.17-2.3 eV).8,13,14 However, the NLO and OL performances of these materials have been less studied so far.In this work, we reported for the rst time the NLO and OL properties of the CH 3 NH 3 PBI 3 perovskite:poly(N-vinylcarbazole) (weight ratio: 1 : 1) blends (CP) in DMF and in the PMMA matrix, respectively, by open aperture Z-scan method. The CH 3 NH 3 PbI 3 perovskite was prepared according to the method described in the literature.6 Poly(N-vinylcarbazole) (PVK, M w ¼ 9 Â 10 ...

“…At the same input pulse energy (e.g., 300 μJ), the annealed PFTP‐RGO/PMMA film exhibits the lowest T min values of 0.10 at 532 nm and 0.18 at 1064 nm (c.f. 0.46 at 532 nm and 0.71 at 1064 nm for RGO/PMMA; 0.22 at 532 nm and 0.36 at 1064 nm for PFTP‐RGO/PMMA), which are much lower than those of other graphene nanostructures (e.g., RGO‐PVK, GO‐PcZn, GONSs, GONRs) . These findings suggest that the annealed PFTP‐RGO/PMMA film shows the best NLO and OL responses among these three film materials.…”

“…Functionalized graphene can be readily doped into solid hosts and is expected to improve the OL performance of the whole system. In our pioneering work exploring graphene‐based OL materials, we were the first to report the OL properties of various graphene nanostructures, including graphene nanosheets, GO nanoribbons, graphene nanoribbons, and GO nanosheets, following our investigation with an open‐aperture Z ‐scan system with nanosecond laser pulses at 532 and 1064 nm . By using the amidation reaction, a GO derivative (GO‐PcZn) covalently modified with a highly soluble zinc phthalocyanine (PcZn) was synthesized .…”

Aggregation-induced emission (AIE) materials are usually not suitable for constructing solid nonlinear optical (NLO) devices because strong solid-state aggregation behavior would shorten the excited-state lifetime, add relaxation pathways, and thereby reduce effective NLO absorption. To address this problem a newly synthesized AIE material, poly{[9,9-bis(6-azidohexyl)-9H-fluorene]-alt-(1,1,2,2-tetraphenylethene)} (PAHFTP), was treated with reduced graphene oxide (RGO) to give the soluble derivative of poly[(9,9-dihexyl-9H-fluorene)-alt-(1,1,2,2-tetraphenylethene)] (PFTP) covalently grafted onto RGO (PFTP-RGO). Upon covalent grafting of PAHFTP onto the RGO surface, about 91.89 % of the fluorescence intensity of the PAHFTP film was quenched due to electron transfer from PFTP to RGO, which yielded PFTP -RGO radical-ion pairs. The as-prepared PFTP-RGO was embedded into a non-optically active poly(methyl methacrylate) (PMMA) matrix to produce the PFTP-RGO/PMMA film with good optical quality. As expected, the PAHFTP/PMMA film did not show any NLO response. In contrast to the PFTP-RGO/PMMA and RGO/PMMA films, the annealed PFTP-RGO/PMMA exhibited superior OL performance, with low OL thresholds of 0.24 GW cm (1.44 J cm ) at 532 nm and 0.18 GW cm (1.08 J cm ) at 1064 nm. The damage thresholds of the annealed PFTP-RGO/PMMA film are around 33.88 J cm at 900 μJ at 532 nm and 37.32 J cm at 1000 μJ at 1064 nm, respectively.
