Claim:
1. A process for preparing an inorganic oxide of formula (I) A a M m (YO 4 ) y Z z (I) in which: A represents at least one element chosen from alkali metals, alkaline-earth metals, a dopant element and a space; M represents (T Y represents at least one element chosen from S, Se, P, As, Si, Ge and Al; Z represents at least one element chosen from F, O and OH; a, m, y and z are stoichiometric coefficients and are real, zero or positive numbers, with the following conditions: a, m, t, y and z are such that the electrical neutrality of the inorganic oxide of formula (I) is respected, a≧0; m>0; y>0 z≧0; starting with precursors of the constituent elements of the inorganic oxide of formula (I), said process comprises the following steps:
