The broad emission band observed in some interstellar environments (e.g., reflection nebulae, planetary nebulae, HII regions, interstellar “cirrus clouds”) extending between about 600 and 800 nm is referred to as extended red emission (ERE). It is thought to be the result of photoluminescence from interstellar dust, although it is not clear whether the carrier is carbon-rich or silicate-rich material. The spatial distribution of ERE is, in many cases, similar to that of polycyclic aromatic hydrocarbons (PAHs).
