“…2, show the existence of three doublets in all three samples. Peak 1 with S 2p 3/2 component at~162.1 eV is attributed to As-S-As fragments connecting the AsS 3 pyramidal units [24], Peak 2 with main component at~163.0 eV is related to S-S-As fragments and Peak 3 with main component at~161.0 eV is assigned to a singlecoordinated sulfur, which can be associated, for example, with dangling bonds or non-bridging sulfur [3]. The latter peak can also originate from S − ions proposed in the vicinity of solvent's −NH 2 complexes throughout the SCF network by Chern and Lauks [18].…”

“…1, for all three compositions As 30 S 70 , As 35 S 65 and As 40 S 60 of SCF indicate the presence of only one chemical environment around As atoms. The position of As 3d 5/2 peak at~43.1 eV is attributed to S-As b (S) 2 (target atom in bold) pyramidal units traditionally associated with bulk As-S glasses [24]. The As XPS spectrum of SCF fundamentally differs from those produced by thermal evaporation.…”

“…XPS has been successfully exploited to determine the structure of a broad range of binary and ternary chalcogenide glass systems, such as As-S, As-Se, Ge-S, Ge-Se, As-Ge-Se, including the chemical environments of the constituent elements [21][22][23][24][25]. It has been used primarily to investigate the structure of thermally evaporated ChG thin films [8,[26][27][28], while such structural information is not available for SCF.…”

Spin-coating technology offers a convenient method for fabricating photostable chalcogenide glass thin films that are especially attractive for applications in IR optics. In this paper we report the structure of spin-coated As x S 100 − x (x = 30, 35, 40) thin films as determined using high resolution X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy, especially in relation to composition (i.e. As/S ratio) and preparation process variables. It was observed that As atoms during preparation have a tendency to precipitate out in close to stoichiometric compositions. The mechanism of bonding between the inorganic matrix and organic residuals is discussed based on the experimental data. A weak interaction between S ions and amine-based clusters is proposed as the basis of structural organization of the organic-inorganic interface.

“…2). The peaks at 193, 232, 330-340 and 493 cm −1 are assigned to various As-S vibrational modes and specifically, the broad peak centered at 340 cm −1 strongly indicates an amorphous arsenic sulfide, or artificial orpiment (g-As 2 S 3 or g-As x S x ) [24][25][26][27][28]. The peak centered at 471 cm −1 is characteristic of free sulfur.…”

Natural and synthetic arsenic sulfide pigments in Japanese woodblock prints of the late Edo period

2018

We recently described the use of an artificial arsenic sulfide pigment in Japanese woodblock prints from the Meiji period : we now expand on our previous work by investigating arsenic sulfide pigments used in Japanese woodblock prints of the late Edo period (1615-1868) and early Meiji period. The series of eight prints A Tour of the Waterfalls in Various Provinces (Shokoku Taki Meguri), by Katsushika Hokusai, issued between 1833 and 1834 is known to have been reproduced from entirely new blocks at some point during the late Edo or early Meiji periods. The two sets, original and copies are characterized by visually distinct color palettes as well as several differences in the image. Two such sets in the collection of the Metropolitan Museum of Art were analyzed with particular attention to the yellow, orange, and green printed areas. X-ray fluorescence spectrometry, Raman microspectroscopy, and scanning electron microscopy-energy dispersive spectroscopy revealed the use of natural orpiment in the original set and of artificial arsenic sulfide pigments in the reproduction set. In addition, the reproduction set features extensive use of ultramarine blue, the synthetic equivalent to lapis lazuli. This pigment, available commercially in Europe from 1830 onward has been documented in Japanese art so far only in a handful of late Edo period paintings. The results of our comparative analysis further highlight differences in pigment use between Edo and Meiji periods, and point to arsenic sulfide pigments as useful markers for the date of original production for popular prints of the Edo period.

“…However, it is well known that corner-shared (CS) units play crucial role in the realistic structure of ChSG too [1]. Thus, the structure of glassy As-S is built exceptionally from such CS units (as it follows, in part, from high-resolution XPS measurements [46]), while in Ge-S glass, Table 1 Bond parameters in geometrically-optimized Ge 2 S 6 H 4 clusters (the constituting atoms are denoted as in Fig. 1).…”
