| Abstract | A luminescence hybrid material, Bis(8-hydroxyquinoline)cobalt(II) (Co(8hq)2), was incorporated into themesoporous silica. To study the preparation of mesoporous silica from rice husk and the development offluorescence efficiency. The mesoporous silica was prepared by swelling-shrinking mechanism which used thesodium silicate from rice husk as the precursor. The hybrid materials were prepared by solid-state reaction at roomtemperature with two different routes; the first one was the hybrid material processes via the in situ formation ofcobalt(II)chloride hexahydrate (CoCl2?6H2O) as well as 8hq into the mesoporous silica (MCM) mixed ground(MCM_Co(8hq)2) and the another one was step by step ground of the mesoporous silica, cobalt(II)chloridehexahydrate and 8hq (MCMCo(II)_8hq). The hybrid materials were characterized by SEM, XRD, FT-IR, AAS,as well as PL. The FT-IR spectra showed the 8hq characteristic at 820, 786, 784, and 747 cm-1 that all of the FTIR spectra shifted to higher frequencies of free 8hq (815, 778, and 739 cm-1), confirming the coordination betweencobalt(II) cation and 8-hydroxyquinoline. The excellent photoluminescence of MCM_Co(8hq)2 revealed at 484nm and MCMCo(II)_8hq demonstrated blue-shifted peak at 474 nm in this comparison, indicating that theformation of different nanostructures and/or packing of bis (8-hydroxyquinoline)cobalt(II) were formed into themesoporous silica |
