The invention belongs to the nano mesoporous material preparation technology field, in particular to the synthesis technology of rare earth aromatic carboxylic acids mesoporous red luminescent material. The invention adopts a two-step method, firstly synthesizing complex which has distinct and stable structure and bright light-emitting, then assembling to the pore passage of MCM-41 mesoporous material, thereby synthesizing red mesoporous material which has stable and high ordered chemical and thermodynamic properties. The process which is provided by the invention is simple and easy to operate, has the characteristics of controllability and quantification. And the rare earth aromatic carboxylic acids mesoporous red luminescent material has long service life and high light-emitting quantum efficiency, regular ordered microcosmic topography, which can be extensively applied on the fields of luminescent material, catalyst material, sorbent material, nano reactor and photoelectric sensor and the like.
