ABSTRACT
In recent years, with the rapid development of ultrastrong and ultrafast lasers, it has become essential to develop new materials with excellent nonlinear optical (NLO) properties. Porphyrin-based metal-organic frameworks (MOFs) have great potential for application in the field of NLO due to their large conjugated structure and good stability. As a typical porphyrin-based MOF, porphyrin paddle-wheel framework-3 (PPF-3) has been prepared and applied in the fields of catalysis and sensing, yet the investigation of PPF-3 in NLO remains unexplored. In this study, the ZnS/PPF-3 composite was successfully prepared using a solvent thermal method to in situ load ZnS on the surface of PPF-3. Utilizing the Z-scan technique, the NLO properties of ZnS, PPF-3, and ZnS/PPF-3 composite were investigated under different input energy intensities. ZnS/PPF-3 composite material exhibits significantly enhanced NLO properties, with the third-order nonlinear absorption coefficient (ßeff) of up to 7.00 × 10-10 m/W and a limiting threshold as low as 1.52 J/cm2, indicating its promising application potential value in the field of optical limiting. To enhance the practical utility, the ZnS/PPF-3/PVA film was prepared via the drop-casting method, achieving a maximum ßeff of 5.00 × 10-8 m/W. The smaller optical bandgap of ZnS/PPF-3 and electron transfer from PPF-3 to ZnS are the key factors that enable the ZnS/PPF-3 composite to a superior NLO performance.
