title: Excellent color rendering index and high quantum efficiency of rare-earth-free fluosilicate glass for single-phase white light phosphor.
abstract: A rare-earth-free Sn-doped fluosilicate (SF) glass for single-phase white light phosphor has been investigated, which has a high color rendering index (98.3) and a quantum efficiency (85%). Moreover, by combining with a 280 nm LED chip directly, the Commission Internationale de l'Éclairage (CIE) coordinate (x=0.32, y=0.33) and correlated color temperature (5620 K) are close to the standard white light illumination. SF glass is a promising candidate as an alternative single-phase white light phosphor for use in general lighting devices.
