A phosphor producing process capable of providing a phosphor of good quality in a reduced period of time. A Li compound acting as a doping agent is added prior to primary calcination so that it may also act as a flux and removed by washing prior to secondary calcination. A ZnO.Ga2O3 solid solution thus obtained is activated in the secondary calcination using an atmosphere in which reducing gas and Zn gas are mixed. Thus, a ZnO.Ga2O3:Li, P phosphor is which the molar ratio between Zn and Ga2O3 is 1:1 and of which crystals exhibit good surface conditions can be produced in a reduced period of time.
