Sequestration of cerium(III) bromide into mesoporous silica

• Mesoporous silica monoliths were synthesized and modified with functional groups.
• CeBr3, a luminescent scintillator was sequestered in the pores of silica monoliths.
• Luminescence showed the differences in coordination environment of the CeBr3.

A variety of surface-functionalized mesoporous silica monoliths were reacted with a cerium(III) bromide molecular complex and a successful scaffold for luminescent materials is demonstrated. The variation in structure of the materials is shown through infrared spectroscopy, and the luminescent properties illustrate the varying coordination environment of cerium(III) bromide.
