“…The enhanced NLA and OL action of C Ag/Au nanohybrids are due to the synergetic effect among the two parent components. [44,45,48,49] Here, the BODIPY molecule acts as an electron donor, and the metal NP acts as acceptor. The outstanding NLA effect of the nanohybrids is attributed to the photo-induced excited sate interaction that leads to the charge/energy transfer, and it is clearly visible in the changes occurred in absorption spectrum, fluorescent spectrum and excited state life time of the system on nanohybrid formation.…”

Materials with large and quick non-linear optical response, excellent photo thermal stability, cost effectiveness and off resonant non-linear absorption (NLA) are essential requirements for a good optical limiting (OL). Among them, organic systems and π-conjugated polymers are getting special interest because of their flexibility in structural modification that leads to the tuning of optical and electronic properties that are suitable for working under large bandwidth. Here, we report a drastic enhancement of non-linear optical activity and exceptional OL action of two organic-inorganic hybrid system based on BODIPY and Au and Ag nanoparticles (NPs). The organic system taken was certain set of BODIPYs with different substitution at the para and meta positions. All the compounds were found to be exhibiting good reverse saturable absorption (RSA) behaviour and negative non-linear refraction property. An attempt was made to improve the non-linear optical (NLO) property of the BODIPY by forming nanohybrids with Au and Ag NPs, and the best NLO active candidate among the studied system was chosen for it. A significant enhancement in NLO property was observed on hybrid system formation. The optical limiting (OL) threshold of the hybrid (1 J/cm 2) was reduced almost 1/5 times than that of the parent compound (5.2 J/cm 2), and this value is comparable with the benchmark OL materials like C 60. The mechanism behind the NLA is found to be the combination of excited state absorption (ESA) and twophoton absorption (TPA). The enhanced NLA and OL action of C Ag/Au nanohybrids are attributed to the synergetic effect among the two parent components as well as the local field effects of NPs. Enhancement in non-linear optical property is found to be stronger in hybrid system with Au NPs and is due to the resonant charge transfer and intense local field effect on exciting with 532-nm pulse compared with that of Ag NPs. Both the parent compounds and the nanohybrids exhibit negative non-linearity, and the non-linear

“…The electron transfer phenomenon also existed when porphyrin was combined with g-C 3 N 4 . Zhu et al reported that the remarkable photoinduced electron transfer (PET) process was observed under visible light irradiation by combining porphyrin with g-C 3 N 4 (Zhu et al, 2020). Thus, combining porphyrin with g-C 3 N 4 might be a feasible method to improve NLO performance.…”

“…Although the aggregation was effectively reduced, but the decrease of the content of porphyrin in the polymer was decreased with the increase of the molecular weight (MW) of porphyrin-based polymer correspondingly, which has a negative influence on NLO property. Other studies showed that porphyrins and nanomaterials were prepared into nanohybrids, and the NLO performance of the nanohybrids could be improved because of the PET between porphyrins and nanomaterials ( Wang et al, 2014 ; Wang A. et al, 2020 ; Fu et al, 2022 ). Consequently, the combination of porphyrin-based polymers and nanomaterials might offer a better solution to further increase the NLO performance of porphyrin-based materials ( Wan et al, 2012 ; Liu et al, 2013 ; Garg et al, 2017 ; Liang et al, 2022 ).…”

In our work, a flurry of original porphyrin-based polymers covalently functionalized g-C3N4 nanohybrids were constructed and nominated as PPorx-g-C3N4 (x = 1, 2 and 3) through click chemistry between porphyrin-based polymers with alkyne end-groups [(PPorx-C≡CH (x = 1, 2 and 3)] and azide-functionalized graphitic carbon nitride (g-C3N4-N3). Due to the photoinduced electron transfer (PET) between porphyrin-based polymers [PPorx (x = 1, 2 and 3)] group and graphite phase carbon nitride (g-C3N4) group in PPorx-g-C3N4 nanohybrids, the PPorx-g-C3N4 nanohybrids exhibited better non-linear optical (NLO) performance than the corresponding PPorx-C≡CH and g-C3N4-N3. It found that the imaginary third-order susceptibility (Im [χ(3)]) value of the nanohybrids with different molecular weight (MW) of the pPorx group in the nanohybrids ranged from 2.5×103 to 7.0 × 103 g mol−1 was disparate. Quite interestingly, the Im [χ(3)] value of the nanohybrid with a pPorx group’s MW of 4.2 × 103 g mol−1 (PPor2-g-C3N4) was 1.47 × 10–10 esu, which exhibited the best NLO performance in methyl methacrylate (MMA) of all nanohybrids. The PPorx-g-C3N4 was dispersed in polymethyl methacrylate (PMMA) to prepare the composites PPorx-g-C3N4/PMMA since PMMA was widely used as an alternative to glass. PPor2-g-C3N4/PMMA showed the excellent NLO performance of all nanohybrids with the Im [χ(3)] value of 2.36 × 10–10 esu, limiting threshold of 1.71 J/cm2, minimum transmittance of 8% and dynamic range of 1.09 in PMMA, respectively. It suggested that PPorx-g-C3N4 nanohybrids were potential outstanding NLO materials.

“…Single-walled carbon nanotubes (SWCNTs) are strips of graphite monolayers (graphene) rolled into cylinders [35]. SWCNTs are promising materials for optical limiting since they have strong nonlinear properties and high photo-and thermal stability [36][37][38][39]. The SWCNTs have a specific absorption spectrum depending on their structural topology and chirality.…”

Nanosecond lasers have recently been widely involved in human activity. However, high-intensity laser radiation can cause severe damage to organs of vision and expensive photonic devices. Radiation in the near UV range is especially dangerous for human eyes, since it is strongly absorbed by biological media and is also invisible, i.e., the reaction time of the eye to such radiation is much lower than that of visible light. Passive limiters have high transmission (>70%) at a low light intensity and begin to “darken” only when the threshold value of the laser radiation intensity is reached. In this work, we studied liquid nanodispersed nonlinear optical limiters based on hybrids of single-walled carbon nanotubes (SWCNTs) with metal-free tetra(hydroxy)phthalocyanine (OH)4PcHH). The value of the hydrodynamic radius of separate particles after (OH)4PcHH binding increased from 288 ± 55 nm to 350 ± 60 nm, which confirms the attachment of phthalocyanine complexes to nanotubes. The third harmonic of a Nd:YAG nanosecond laser (355 nm, 20 ns) was used to study the nonlinear optical response. Based on a Z-scan with open-aperture and input-output dependence curves, third-order nonlinear optical absorption coefficients of 149, 236, and 229 cm/GW were obtained for dispersions of composites of SWCNTs and (OH)4PcHH in water, dimethylformamide (DMF), and dimethylsulfoxide (DMSO), respectively. Threshold values did not exceed 100 mJ/cm2. The Z-scan showed a gradual decrease in the duration of the laser pulse by 53%; however, near the focus, there was a sharp increase in the duration of the transmitted pulse, reaching a value of 29 ns in z = 0. This phenomenon confirms the occurrence of reverse saturable absorption in the investigated media and can be used in photonic devices to control the temporal characteristics of the signal. Thus, the possibility of protection of sensitive photonic devices and human eyes from nanosecond laser pulses in the near UV range by nanodispersed liquid media based on composites of SWCNTs with (OH)4PcHH has been discussed in this paper.
