| Abstract: | Absorption spectra of GaAs nano-particles compound thin films with different diameter of GaAs particles have been measured and studied. The blue-shift of the absorption edge of the compound films were observed comparing to that of bulk GaAs crystal. The blue-shift value of 1.16eV was obtained in the films with diameter of (3.2nm) GaAs nano-particles. |
