Abstract
NiTi Shape Memory Alloy (SMA) is now widely used in important applications due to its shape memory effect (SME) and biocompatibility. However, there is still a challenge to control the sizes and shapes of these nanoparticles. Here, we report on the use of pulsed laser deposition technique for the cultivation of NiTi nanoparticles on glass substrates. It discussed the implications of the case of the influence of depositing laser energy on the size of a grain of NiTi nanoparticle. The nominated effect on the optical properties of its thin-film was also discussed. X-ray diffraction (XRD) analysis revealed that the films prepared at 800[Formula: see text]mJ, 900[Formula: see text]mJ and 1000[Formula: see text]mJ were amorphous structures. The Atomic Force Microscopy (AFM) results confirmed that the thin films are made up of spherical particles that are evenly distributed (in terms of size). A blueshift in the bandgap was observed in the UV–Visible absorption spectra with increase in the depositing laser energy due to the quantum confinement effect of nanoparticle formation.
