Novel　luminescent　hybrid　silicas　have　been　synthesized　through　one-step　and　two-step　methods　and　their　different　luminescent　properties　have　been　investigated.　The　results　showed　that　the　samples　synthesized　with　two-step　procedure　exhibited　a　more　evident　blue　shift　of　photoluminescence　performance　resulting　from　the　high　efficiency　of　surface　amine　than　that　by　one-step　route.　The　structure　characteristic　and　texture　properties　of　resultant　hybrid　silicas　were　characterized　by　XRD,　TEM,　FT-IR　and　N-2　adsorption-desorption　techniques,　indicating　that　inorganic/organic　nanocomposites　could　maintain　the　bimodal　mesoporous　structure.　Finally,　a　possible　involved　mechanism　has　been　put　forward.　(C)　2010　Elsevier　B.V.　All　rights　reserved.
