Nickle　tetrasulfo-phthalocyanine　(NiTSPc)　and　Lead　phthalocyanine　(PbPc)　are　introduced　respectively　into　silica　gel　glass　matrix　by　sol-gel　technique.　Homogeneously　doped　composites　are　produced,　and　optical　limiting　examination　was　carried　out.　The　results　show　that　the　change　in　matrix　composition,　structure　and　sol-gel　process　will　influence　the　chemical　micro-environment　and　excited　state　physical　process　of　doped　metallo　phthalocyanine,　resulting　in　the　change　in　composite＇s　optical　limiting　behaviors.
