Abstract
A glass emitting white light in itself, and a light-emitting element and a light-emitting device covered with the glass as stated above are provided. The white light-emitting glass is a glass emitting fluorescence at a region having a wavelength of 380 nm to 750 nm by excitation light with a wavelength of 240 nm to 405 nm, not containing crystal, and containing SnO(where x=1 to 2, typically x=1 or 2), PO, and MnO(where y=1 to 2, typically y=1 or 2). The light-emitting element and the light-emitting device are made up by covering a main surface of a semiconductor light-emitting element with the glass as stated above.
