This invention provides a fluorescent substance composite glass, which is chemically stable, has a large size and a small thickness, is uniform in thickness, and, at the same time, has a high energy conversion efficiency, and a fluorescent substance composite glass green sheet and a process for prooducing a fluorescent substance composite glass. The fluorescent substance composite glass is produced by baking a mixture comprising a glass powder and an inorganic fluorescent substance powder and is characterized in that, when light having a luminescence peak in a wavelength region of 350 to 500 nm is applied, the efficiency of conversion of energy to a visible light wavelength region of 380 to 780 nm is not less than 10%. |
