摘要：

Europium　chloride　was　employed　to　modify　1,　8-naphthalic　anhydride(NA)　loaded　on　bimodal　mesoporous　silicas　(BMMs),　and　hopefully　to　improve　its　luminescent　performance.　The　structural　features　of　the　obtained　hybrids　nanomaterilas　were　characterized　by　means　of　XRD,　TEM,　N2　adsorption-desorption,　FT-IR,　TG　techniques,　and　their　luminescence　properties　were　investigated　with　help　of　photoluminescence　(PL)　measurements.　The　results　showed　that　the　bimodal　mesopores　of　BMMs　could　be　preserved　after　functionalization　via　grafted　Eu3+-modified　NA　molecules.　Meanwhile,　the　influences　of　the　addition　amount　of　EuCl3　on　the　luminescence　performances　were　remarkable,　with　both　of　slight　blue-shiftness　of　emission　peak　and　obvious　enhancement　of　luminescent　intensity.
