PROBLEM TO BE SOLVED : To provide an inorganic composition including a rare earth metal or/and a transition metal in the fourth period dispersed in an inorganic matrix having long-term light resistance and heat resistance with high concentration and uniformity, and a process for producing them at a low temperature and with easy moldability. SOLUTION : The inorganic composition includes at least one rare earth metal or/and a transition metal in the fourth period dispersed in the inorganic matrix, wherein a dispersed phase including the rare earth metal or/and the transition metal in the fourth period, to which another metal species is coordinated via oxygen, is formed.
