Abstract
Provided is a glass that is used in a phosphor-containing wavelength conversion material and from which can be produced a wavelength conversion member less degraded in characteristics of a phosphor owing to firing during production of the wavelength conversion member and having excellent weather resistance. The glass is for use in a wavelength conversion material and contains, in terms of % by mass, 30 to 75% SiO, 1 to 30% BO, over 4 to 20% AlO, 0.1 to 10% LiO, 0 to below 9% NaO+KO, and 0 to 10% MgO+CaO+SrO+BaO+ZnO.
