Precise structural design of a host-guest complex was carried out from the aspects size and location guest (anatase particles), remaining open space host (mesoporous silica). The anatase particles successfully controlled (3, 5 8 nm) during preparation, size-controlled nanoparticles were preferentially encapsulated into mesopores with diameter nm. Due to precise control particles, dependent photoluminescence quantum dots observed for first time. change in porosity mesoporous silica by immobilization pore followed find systematic variation corresponding loaded amount. This correlation can be useful estimate in/on hybrids.
