By using SRIM-2012 program the Gauss profile on depth distribution of implanted ions in the As2S3 matrix is calculated, showing depth of ion distribution at the sample surface on the level ~ 60 nm; similar results are obtained for the Ge15.8As21S63.2 ChVS; in contrast to virgin matrix, implanted sample Cu:As2S3 is characterized by an existance in the visible spectral region the selective absorption band with maximum ~ 580-590 nm; this band shows on the formation of copper nanoparticles in As2S3; this band is originated due to surface plasmon resonance (SPR) effect in metal nanoparticles; SPR-absorption of metal nanoparticles in the transmission spectra of Cu:Ge15.8As21S63.2 sample is slightly detectable, but the concentartion of copper, determined by ion dose, in the Ge15.8As21S63.2 ChVS matrix is still high to be enough for the growth and formation of copper nanoparticles.
