Laser printing technique offers an effective, fast process and free of lithography for fabricating spherical nanoparticles. on the other hand, GeSbTe (GST) compound has attracted a lot of attention in the field of reconfigurable metamaterials. Here, we use this method to fabricate the spherical GST nanoparticles. Transmission electron microscopy (TEM) analysis of the GST nanoparticles shows a broad size distribution of spherical nanoparticles which makes them resonant in wide spectral range. We also study the nonlinear optical properties of the nanoparticles demonstrating a sharp increase of second harmonic generation (SHG) at the transition point from amorphous to crystalline states.
