摘要：

A coordination and copolymerization strategy was adopted to synthesize bonded Eu(III) polymer phosphor poly(MMA-co-Eu(BTZ)(2)(Phen)(UA)) (PM-Eu for short) with methyl methacrylate (MMA) as polymer matrix and Eu-complex monomer Eu (BTZ)(2)(Phen)(UA) using azodiisobutyronitrile as initiator. The copolymer PM-Eu exhibits thermal stability up to 266 degrees C. It also exhibits wide and strong excitation bands from 230 to 380 nm monitored at 612 nm, matching well with the 365 nm of ultraviolet (UV) chip. PM-Eu displays Eu(III) characteristic peaks at 579, 591, 612, 650, and 700 nm under the excitation of 365 nm of UV light. Meanwhile, it has a fluorescence lifetime of 0.582 ms, and it has a higher quantum yield of 0.672. All the results prove that the polymer PM-Eu can be applied as a red component for fabrication of near UV-based white light-emitting diode (LED).
