- Abstract
Indium nitride InN nanoparticles NPs suspension prepared by Nd:YAG laser ablation of indium target submerged under ammonium hydroxide. The Scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy, UV/VIS/NIR spectrophotometer and Conductivity meter were used to determine the properties of the nanoparticles prepared with different laser conditions. Fourier transform infrared spectra exhibit the presence of In = N and In–N bonds, which indicates the formation of InN particles. X-ray diffraction pattern observed in the formation of InN NPs with cubic phase, the average diameters of the dominant peak c-InN (101) were approximately 2 nm. Scanning electron microscopy image shows the presence of a large number of spherical shape nanoparticles having a particle size in the range 2–40 nm with a few individual nanoparticles larger than 128 nm. The transmission spectra of InN NPs suspension have the maximum optical transmission edge at 1378 nm with bandgap energy was 0.85–1.2 eV. InN has high electrical conductivity that depends on temperature value with small activation energy at room temperature ranging from 0.0318 meV to 0.1591 meV.
