We present electronic and optical properties of the hydrogen terminated gallium arsenide nanoparticles using time dependent density functional theory (TD-DFT). The electronic and optical properties of the GaAs nanoparticles were calculated at presence of the uniform external electric field in the range from 0 to 0.51 V/angstrom. The induced electric filed can decrease the HOMO-LUMO gap of the nanoparticles and the mount of these reductions increases with gain of the electric field strength.
