Ordered mesoporous materials with its pore structure, a variety of topologies, adjustable aperture size, controlled morphology, high specific surface area and large pore volume and other advantages, in catalysis, bio-medicine, energy , sensing, material synthesis and other fields has been widely used. In recent years, mesoporous materials with optical, electrical, magnetic and other features combine to make it suck - desorption, storage, transmission, tracer, targeting has played a greater role. Rare earth elements with special electronic and optical properties, is an important component of the luminescent material. This article will luminescence properties of rare earth material itself and mesoporous, ordered the combination of the structural properties, to carry out the synthesis mediated Faguang materials research to develop rare earths and the synthesis of mesoporous materials, new methods and areas of application. A study of the ordered mesoporous structure doped with rare earth phosphate synthesis and luminescence properties of different rare earth ions. In hard template prepared mesoporous material based on the method proposed multicomponent insoluble solid compound precursor solution preparation new method, so that the insoluble solid compound was dissolved to obtain a homogeneous and stable precursor solution by capillary action the precursor into hard template pores accumulated precipitation, after roasting and remove silicon obtained after inverting the copied template mesoporous yttrium phosphate, by doping europium, terbium, cerium different luminescent ions, get hair red, green, blue three mesoporous rare species YPO4: Ln3 (Ln: Eu, Tb and Ce), by varying the doping concentration of Ln, and luminescent properties of the rare earth phosphate regulation. 2, the use of improved hard template synthesized nanocrystals of two-dimensional hexagonal (p6mm) and three-dimensional cubic (Ia3d) mesoporous rare earth vanadate, the effects of different topologies mesoporous mesoporous yttrium vanadate (Eu ) luminescent properties. Studies showed that the two mesoporous yttrium vanadate (Eu) is strongest in the light emission of Eu3 + doped different concentrations; in three-dimensional cubic mesoporous yttrium vanadate (Eu) and, Eu3 + concentration is most suitable for 8% (mol) ; the two-dimensional hexagonal mesoporous yttrium vanadate (Eu) and, Eu3 + concentration is most appropriate 5% (mol). Analysis of the various defects caused by mesoporous structure, such as the effective area exposed to light of the fluorescent central ion (Eu3) impact. 3, the study of ordered layered organic - inorganic hybrid RE cerium phosphate (Tb) synthesis and luminescence properties. Studies show that, in the synthesis process using water as the polar solvent, the prepared samples have good crystallinity and orderly layered structure, the luminous intensity is far higher than that prepared by precipitation of the solid powder and with a very of the smaller sample prepared in ethanol as solvent. Description ordered crystalline layered structure and good favor some rare earth cerium phosphate inorganic (Tb) of the light. Meanwhile, such a hybrid long alkyl luminescent material also has lipophilic, when dispersed in an organic solvent can be issued when a strong green. 4, rare earth oxides supported on spherical, polyhedral, bar various morphologies mesoporous silica composite prepared. By changing the temperature, load and other factors investigated carrier silica morphology, pore structure on the luminescent properties of the load, and found several different morphologies of calcination temperature on the impact of roughly the same compound, the temperature is too high will cause the pore collapse, after calcination at 1000 ℃, mesoporous rare-earth oxide is destroyed and a phase transition with the template. Spherical carrier minimum load capacity of rare earth oxides, rod carrier load capacity maximum load capacity of the carrier polyhedron between the former two of them. Rare earth oxide on the carrier in different light conditions with different laws. Topological structure of mesoporous materials varied, in order to adapt to future applications finer, more specific needs, a different structure and impact of the differences brought about further research is needed. In this paper, with a variety of topologies mesoporous rare earth composite luminescent materials were studied and compared the performance of the hope for the preparation of rare earth materials multifunctional do useful work.
