Highly split room-temperature visible light emissions (335 to 650nm) were observed from Si-rich oxide films that had been deposited from a plasma phase mixture of silane and O2. Photoluminescence bands at 365 and 469nm were attributed to the E’ center and the neutral O vacancy, respectively. Relatively sharp peaks at 403 and 535nm were related to the development of a Si-enriched polycrystalline core.
