Study of platinum impurity atom state in vitreous arsenic selenide

Abstract: Platinum atoms in the structure of As 2 Se 3 glass are stabilized in the form of Pt 2+ and Pt 4+ ions and correspond to ionized states of the amphoteric two electron center with negative correlation energy (Pt 2+ is an ionized acceptor, and Pt 4+ is an ionized donor), whereas the neutral state of the Pt 3+ center appears to be unstable.

“…When introduced into a glass-forming matrix, admixture atoms rebuild their local environment resulting in the saturation of their valence bonds. Exceptions are the admixtures of bismuth, platinum, and gold into arsenic sulfide [4][5][6].…”
