Optical gain in gallium selenide and indium selenide
Physica B+C, 1981Abstract The stimulated emission at 80 K from layered single crystals of GaSe and InSe has been studied at high excitation density by means of nitrogen and dye laser, respectively. On both the semiconductors we observe the stimulated emission associated with exciton-exciton scattering.

Photoconductivity of Indium selenide
Vacuum, 1953Indium selenide layers have been formed by successive evaporations of indium and selenium and by direct evaporation of indium selenide. The films are photoconductive with a long wavelength cutoff at about 2 microns and peaks in their spectral response at 0.6 and 1.4 microns. A different time constant is associated with each peak.

Phase studies in the system mercury selenide - manganese selenide
Materials Research Bulletin, 1977Abstract HgSe forms solid solutions with MnSe while retaining the sphalerite structure. The solubility limit as determined from lattice constant measurements is 38.5 mol % MnSe at 700°C. No detectable solubility of HgSe in rocksalt type MnSe could be observed. The phase relationships within the region of HgSe solid solution are given based on DTA and

Hydrogen selenide and methylselenol
1987Publisher Summary Hydrogen selenide and related forms of selenium are difficult to handle. The absence of direct methods for identification of H2Se led to develop a method based on the use of Sanger's reagent (1-fluoro-2,4-dinitrobenzene, FDNB) to trap H2Se in a stable form upon volatilization from acid medium in a stream of nitrogen.

The complexing characteristics of insoluble selenides. II. Manganese selenide
Journal of the Less Common Metals, 1970Abstract The aqueous solubility of manganese selenide determined at 25 °C and unit molar ionic concentration has revealed the formation of only free manganese ions and a complex aqueous species [Mn(HSe)(OH)]in the supernatent phase in contact with the insoluble compound. The solubility product of MnSe and the stability constant of the complex species

The complexing characteristics of insoluble selenides. 1. Silver selenide
Canadian Journal of Chemistry, 1970The aqueous solubility of the system silver selenide has been investigated in an inert atmosphere of nitrogen at a unit molar ionic strength and constant temperature of 25° C. The experimental evidence indicates the formation of two aqueous species [Ag2(HSe)(OH)], and [Ag(Se)2(OH)]4− in contact with the precipitated selenide in different regions of ...

Metabolism of Hydrogen Selenide and Methylated Selenides
1979Inorganic forms of selenium are readily metabolized to a variety of or-ganoselenium compounds in microorganisms, plants, and animals. The metabolism of selenium may either enhance or reduce the biological activity of this element. Nutritionally active inorganic selenium compounds, such as sodium selenite or sodium selenate, can be converted to ...
