PROBLEM TO BE SOLVED : To provide a new method for producing a rare earth silicate phosphor. SOLUTION : The method for producing the phosphor represented by the compositional formula, LuxYyGdzSiOp : aA, bL comprises the steps of (1) adding a silicon alkoxide and a compound of an activator element to an alkoxy alcohol additive of a rare earth carboxylate and then mixing them, (2) causing water to act on the thus obtained mixed solution so as to gel the mixed solution, and (3) pyrolyzing the thus gelled product.
