Abstract

The chalcogenide glass (ALS, $Al_2S_3-La_2S_3$) was prepared by melting a stoichiometric mixture of aluminum powder and $La_2S_3$ under $H_2S$ atmosphere at $1200{\circ}C$. Glasses containing 0.1-0.1% of $Mn^{2+},\;Gd^{3+}$ and $Cu^{2+}$ were also prepared. The characteristic features of the ESR spectra for the transition metal containing ALS glasses are interpreted.
