Synthesis and photophysical properties of a highly luminescent Eu III -containing hybrid thin film

Abstract

A luminescent thin film, Eu@glass, has been prepared on the surface of glass substrates from a silylated diamidopyridyl ligand L and the complex [Eu(dbm) 3 (H 2 O) 2 ] (Hdbm = dibenzoylmethane) via a sol-gel method. The Eu@glass exhibits intense red photoluminescence under the irradiation of near UV light with a quantum yield of 26%. Compared to the compound [Eu(dbm) 3 (H 2 O) 2 ], the photoluminescence intensity of Eu@glass is dramatically enhanced, and the emission lifetime of Eu III (0.517 ms) more than an order of magnitude longer.
