The sample was comprehensively characterised through UVvisible spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM). XRD pattern for the sample revealed a face-centered cubic crystalline phase of platinum, with a lattice constant of 3.939 The average particle size, obtained from high-resolution electron microscopy analysis, is 3.73 nm. The third order NLO features were explored through the Z-scan technique, employing a continuous wave regime. The observed phenomena of nonlinear absorption (NLA) and nonlinear refraction (NLR) are attributed to reverse saturable absorption and thermal lens models. NLR index was measured to be in the range of 5.72 10?10 cm2/W, while NLA coefficient was found to be in the range of 1.86 10?5 cm/W, highlighting the potential of PEGylated Pt NPs for NLO applications. 2025 Elsevier B.V.
