In　this　study,　a　new　europium　complex　of　4,4＇-bis　(1　＇＇,1　＇＇,1　＇＇,2　＇＇,2　＇＇,3　＇＇,3　＇＇-heptafluoro-4　＇＇,6　＇＇-hexanedion-6　＇＇-yl)-o-terphenyl-Eu3+-4,7-diphenyl-1,10-phenanthroline-2,9-dicarboxylic　acid-(3-aminopropyl)trimethoxysilane　(BHHT-Eu3+-DPPDA-APTMS)　was　prepared　first.　Then　novel　core　shell　Ag@SiO2　nanoparticles　with　BHHT-Eu3+-DPPDA-APTMS　doped　in　shell　were　synthesized　by　a　facile　water-in-oil　microemulsion　method.　The　properties　of　the　prepared　complex　and　nanoparticles,　and　the　effect　of　metal　enhanced　fluorescence　for　the　nanoparticles　were　investigated.　The　prepared　nanopartilces　exhibited　intense　fluorescence,　uniform　morphology　and　good　water-solubility.　The　fluorescent　intensities　of　silver　core-present　nanopartciles　were　significant　higher　than　that　of　silver　core-absent　nanoparticles　owing　to　the　metal　enhanced　fluorescence　of　silver　core.　It　is　expectable　that　the　as-prepared　nanoparticles　can　serve　as　a　potential　fluorescent　nanoprobe,　applying　in　high　sensitive　biological　and　medical　detections.
