 In this paper, the synthesis of titanium nitride (TiN) nanoparticles has been investigated by using Ce:Nd:YAG pulsed laser ablation method. A pure tablet of TiN (with 99.99% purity) was stabilized in toluene and exposed to the fundamental harmonic pulse radiation of Ce:Nd:YAG laser operating at 1064 nm wavelength with the pulse width of 8 ns and a repetition rate of 10 Hz. The synthesized NPs were characterized by UV-Visible absorption spectroscopy, Fourier transform (FTIR) spectroscopy, Raman spectroscopy, X-ray diffractometery (XRD) and Transmission electron microscopy (TEM), techniques. The XRD patterns and FTIR spectra reveal the formation of TiN NPs in the sample. One of the most important properties of the TiN NPs are the plasmonic characteristics of these NPs, but the UV-Vis spectroscopy showed that the synthesized nanoparticles did not exhibit plasmonic properties, and it was found that the absence of plasma peak in the absorption spectrum was due to the formation of the carbon matrix halation, which in the result, is the interaction of the laser with hydrocarbon bonds in toluene, which eventually surrounds the carbon of TiN NPs. The Raman spectra also confirmed the presence of carbon halation as a graphite matrix on NPs.
