LIGHT-EMITTING LAMINATE

摘要

A light-emitting laminate wherein a phosphor layer composed of a phosphor which emits visible light when excited by ultraviolet light having a wavelength within the range of 230-260 nm is formed on a base.  The light-emitting laminate is characterized in that (1) a wavelength conversion layer composed of a sintered magnesium oxide powder which emits ultraviolet light having a peak within the wavelength range of 230-260 nm when excited by ultraviolet light produced by Xe gas discharge is formed under the phosphor layer; (2) a sintered magnesium oxide powder which emits ultraviolet light having a peak within the wavelength range of 230-260 nm when excited by ultraviolet light produced by Xe gas discharge is added into the phosphor layer; or (3) a phosphor protective layer composed of a sintered magnesium oxide powder which emits ultraviolet light having a peak within the wavelength range of 230-260 nm when excited by ultraviolet light produced by Xe gas discharge is formed on the phosphor layer.
