White luminescent hybrid soft materials of lanthanide (Eu3 +, Sm3 +) beta-diketonates and Ag/Ag2S nanoparticles based with thiol-functionalized ionic liquid bridge

Abstract

Thiol-ionic liquid (SHIL) is prepared and used as bridge to prepare multi-component soft hybrids materials Ag(Ag2S)-SHIL-Ln(L)4 (Ln=Eu, Sm, L=TTA (thenoyltrifluoroacetylacetone), TAA (trifluoroacetylacetone), DBM (1,3-diphenyl-1,3-propanepione)) for its good solubility and functionality. Luminescence color of these soft hybrid materials can be adjusted through controlling different proportion of beta-diketonates (TTA, TAA, DBM) and silver species (Ag, Ag2S). Especially the white luminescence can be realized for the special composition of Ag/Ag2S and lanthanide beta-diketonate. The result can be expected to prepare luminescent soft materials to obtain the multi-color and white luminescence.
