Abstract

For the first time copper nanoparticles were formed inside Cu ion-doped glass after infrared irradiation by a nanosecond laser and sucessive annealing at 700 degrees C for 1 h. The surface plasmon resonance was observed in the absorption spectra of copper nanoparticles. Their spectral position is in good agreement with the values predicted by Mie theory for the copper nanoparticles. The possible mechanisms responsible by the observed results are discussed.
