Abstract: Mesoporous material MCM-41 was prepared at room temperature, then rare earth ion Eu and semiconductors CdS were assembled in the channel of MCM-41. The CdS/Eu-MCM-41 samples were characterized by XRD, FTIR, nitrogen adsorption, UV-Vis and fluorescence measurement. Results show that the CdS/Eu-MCM-41 samples possess the mesoporous MCM-41 structures with ordered hexagonal arrangement after Eu3+ and CdS was assembled in the channel of MCM-41. In addition, an obvious blue shift was observed and the luminescence characteristics of the assembled CdS/Eu-MCM-41 were intensified.

Key words: mesoporous material, channel, assembly, luminescence
