Notably, lead chalcogenide NQDs, especially PbSe NQDs, provide efficient emission over a large spectral range in the infrared, but their application has been limited by instability in emission quantum yield and peak position on exposure to ambient conditions.
Galena Mineral Information photos and Facts, sulfide Lead Ore
Veins of galena containing silver (silverlead) are probably produced by ascending hot water solutions emanating from bodies of igneous rocks, while the galena in limestone was probably deposited by groundwater that dissolved the sulfide from the surrounding sedimentary and metamorphic rocks. Galena occurs very widely spread.
