Dysprosium(III) sulfide is a binary inorganic compound of dysprosium and sulfur with the chemical formula Dy2S3.[1][2][3][4]
Dysprosium(III) sulfide can be produced by treating metallic dysprosium with sulfur:
- 2Dy + 3S → Dy2S3
Once prepared, dysprosium(III) sulfide can be purified by chemical vapor transport using iodine.[5]
Dysprosium(III) sulfide can also be prepared by treating dysprosium sulfate with hydrogen sulfide at elevated temperatures:[6]
- Dy2(SO4)3 + 12 H2S → Dy2S3 + 12 H2O + 12 S
