barium sulfide
Quick Summary
Barium sulfide (BaS) is a chemical compound, specifically a sulfide of barium. It is typically a gray to black substance, though it can be colorless and crystalline. Barium sulfide is produced by reducing barite with coal and is used in the creation of other barium compounds, pigments like lithopone, and luminous paints. It's important to note that all soluble barium compounds, including barium sulfide, are toxic to mammals.12

photochemical reactionHistory… sulfate with charcoal to synthesize barium sulfide. Exposure to sunlight caused the phosphor to emit a long-lived yellow glow, and it was sufficiently regarded that many traveled to Bologna to collect the mineral (called Bologna stones) and make their own phosphor. Subsequent work by Italian astronomer Niccolò Zucchi in 1652…

luminescenceLuminescent materials and phosphor chemistry…synthesized was probably an impure barium sulfide preparation with very low luminance efficiency and with the serious shortcoming that it was rather quickly decomposed in moist air, yielding hydrogen sulfide. A more stable sulfide-type phosphor was produced in 1866 by heating zinc oxide in a stream of hydrogen sulfide. In…
