Investigation of some photoelectric and luminescence properties ofγ-La₂S₃single crystals

Abstract

An investigation was made of the photoconductivity, photoluminescence, and thermally stimulated currents in undoped y-hs^S, single crystals. The energy positions of centers with deep levels were identified. The participation of these centers in the radiative recombination process was considered.

Comparative optical studies of Ce2S3 and Gd2S3 compounds

“…A distribution of shallow states just below the conduction band edge has indeed been deduced from luminescence and photoconductivity measurements in ␥-La 2 S 3 single crystals, and ascribed to the presence of cation vacancies distributed at random on the La sub-lattice. 22 FIG. 4.…”

A Self‐Sacrificing Template Route to Spinel MIIIn2S4 (MII = Mn, Zn, Cd, Fe, Co, Ni) and MIIn5S8 (MI = Cu, Ag) Porous Microspheres

“…electro-photographic films, switches, optical filters, photodetectors, magnetic field control lasers, light modulators, optoelectronics, and Schottky diodes). [14][15][16][17][18] The type I-III-VI ternary semiconductors Cu-In 5 S 8 and AgIn 5 S 8 are also of great technological and scien- tific interest because of their possible application in semiconductor devices and optical and quantum electronics. [19] Both M II In 2 S 4 and M I In 5 S 8 show n-type conductivity and crystallize in the spinel-type cubic structure with the space group Fd3 ¯m.…”
