| 摘 要： | Novel ordered mesoporous Eu（DBM）3phergAPTES-SBA-15 （EAS） composites with reasonable photoluminescence property and interesting morphology of bundles of pearl-like chains were synthesized. The characteristics of the mesostructure and the optical properties of the prepared samples were investigated by means of XRD, FTIR, SEM, TEM, N2 adsorption-desorption and PL spectroscopy. The results indicate that the as-made EAS composites have long-distance ordered mesoporous structure. Compared with the Eu（DBM）3phen complex, it is found that the EAS composites perform a considerable photoluminescence with good color purity. It is proposed that the anchored amin~ from the APTES and quantum size effect of the Eu（DBM）3phen complex have great effect on the photoluminescence of the EAS composites.

| Abstract: | Novel ordered mesoporous Eu(DBM)3phen/APTES-SBA-15 (EAS) composites with reasonable photoluminescence property and interesting morphology of bundles of pearl-like chains were synthesized. The characteristics of the mesostructure and the optical properties of the prepared samples were investigated by means of XRD, FTIR, SEM, TEM, N2 adsorption-desorption and PL spectroscopy. The results indicate that the as-made EAS composites have long-distance ordered mesoporous structure. Compared with the Eu(DBM)3phen complex, it is found that the EAS composites perform a considerable photoluminescence with good color purity. It is proposed that the anchored amine from the APTES and quantum size effect of the Eu(DBM)3phen complex have great effect on the photoluminescence of the EAS composites. |
