|Applicants:||KONOSHIMA CHEMICAL CO., LTD.
Provided is a ceramic composition which can impart a light scattering function while keeping the optical properties thereof at high levels. The ceramic composition is composed of a fluorescent phase formed of a fluorescent material and a light-scattering phase formed from a lanthanum oxide. The lanthanum oxide may comprise, for example, at least one compound selected from LaAlO3 and La2O3. The ratio of the fluorescent material (or the fluorescent phase) to the lanthanum oxide (or the light-scattering phase), i.e., the (former)/(latter) ratio (by volume), may be 99.9/0.1 to 50/50.
