摘要：

The　organic-inorganic　luminescent　hybrid　mesoporous　materials　(LHMS)　was　prepared　via　aminopropyl　groups　modification　and　subsequently　1,8-Naphthalic　anhydride　loading　by　using　bimodal　mesoporous　materials　(BMMs)　and　MCM-41　as　carriers,　respectively.　The　resultant　hybrid　materials　were　characterized　by　XRD,　TEM,　SEM,　BET,　FT-IR　and　PL　methods.　It　was　showed　that　the　emission　peak　position　of　LHMS-BMMs　is　around　444　nm,　while　for　LHMS-MCM-41　with　about　450　nm,　demonstrating　that　the　blue-shift　phenomenon　of　LHMS-BMMs　was　more　remarkable　than　that　of　LHMS-MCM-41.　The　most　reason　is　the　different　morphology　and　related　particle　sizes　between　BMMs　and　MCM-41:BMMs　is　of　spherical　particle　with　a　size　of　around　50　nm　and　uniform　mesopores　(about　3　nm),　while　MCM-41　reveals　irregular　particle　distribution　in　the　range　of　1-3　μm,　but　with　uniform　one-dimensional　mesopores　(about　3　nm).
