Indium Sulfid (III) (In2S3)-Pellets

Characteristic

Indium(III) sulfide (Indium sesquisulfide, Indium sulfide (2:3), Indium (3+) sulfide) is the inorganic compound with the formula In₂S₃.

Chemical formula：In2S3

Molar mass：325.82 g·mol⁻¹

Appearance：red powder

Density：4.90 g cm⁻³, solid

Melting point：1,050 °C (1,920 °F; 1,320 K)

Solubility in water：insoluble

Application

Photovoltaic and Photocatalytic

Thin films β-In₂S₃ can be grown with varying band gaps, which make them widely applicable as photovoltaic semiconductors, especially in heterojunction solar cells.

Biomedical

A preparation of indium sulfide made with the radioactive 113In can be used as a lung scanning agent for medical imaging. It is taken up well by lung tissues, but does not accumulate there.

Other

In₂S₃ nanoparticles luminesce in the visible spectrum. Preparing In2S3 nanoparticles in the presence of other heavy metal ions creates highly efficient blue, green, and red phosphors, which can be used in projectors and instrument displays.
