Kinetic analysis of the crystallization processes in the glasses of the Bi–As–S system

Analysis of electrical parameters of the glasses of the system Bix(As2S3)100−x

“…to the increase in the degree of disorderliness of the amorphous network. On the other hand, previous DSC studies indicated the existence of a complex crystallization process [19]. Hence, a significant increase in the conduction for the compositions with higher Bi contents, accompanied by a change in the dominating mechanism of transport of charge carriers, could be explained in terms of the phenomenon of phase separation.…”

Photoinduced transformations in (As1–xBix)2S3 glass observed by Raman spectroscopy

“…x Bi x ) 2 S 3 with lower content of bismuth upon thermal annealing. 33 A separate study of the influence of photodiffusion as well as As!Bi substitution on the optical properties was carried out for Bi/As 2 S 3 bilayer thin films. 34 An excellent tool to study photoinduced effects in amorphous materials is Raman spectroscopy, in particular, to monitor phase separation or photochemical transformations due to the light-matter interaction.…”

“…Therefore, it cannot be excluded that upon illumination of a (As 1– x Bi x ) 2 S 3 glass photoenhanced diffusion can result in the formation of Bi 2 S 3 nanocrystals. Besides, Bi 2 S 3 nanocrystals were reported to be formed in amorphous (As 1– x Bi x ) 2 S 3 with lower content of bismuth upon thermal annealing 33 . A separate study of the influence of photodiffusion as well as As→Bi substitution on the optical properties was carried out for Bi/As 2 S 3 bilayer thin films 34 …”

Vitreous arsenic sulfide doped with bismuth bromide

“…In addition to this, As 2 S 3 is a fine matrix for cations of rare earth and transition metals that provide the vitreous material with special electrical, thermophysical, mechanical, and magnetic properties [3]. The introduction of post transition metals (specifically, bismuth [4]) into As 2 S 3 allows one to synthesize glasses with even more practi cally relevant properties [5]. The present study was aimed at characterizing the physicochemical proper ties of glasses obtained by introducing bismuth in an ionic state (as an alternative to its introduction in an elementary form).…”
