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°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).

粘结的Eu（III）聚合物荧光粉用于白色发光二极管的合成和发光性能

采用配位和共聚策略合成了以甲基丙烯酸甲酯（MMA）为聚合物基体的键合Eu（III）聚合物荧光粉聚（MMA-co-Eu（BTZ）₂（Phen）（UA））（简称PM-Eu）和Eu复合单体Eu（BTZ）₂使用偶氮二异丁腈作为引发剂的（Phen）（UA）。共聚物PM-Eu表现出高达266°C的热稳定性。它还在612 nm处检测到230至380 nm的宽和强激发带，与365 nm紫外线（UV）芯片非常匹配。在365 nm的紫外光激发下，PM-Eu在579、591、612、650和700 nm处显示Eu（III）特征峰。同时，其荧光寿命为0.582ms，并且具有更高的量子产率0.672。所有结果证明，该聚合物PM-Eu可以用作制造基于紫外线的白色发光二极管（LED）的红色组分。
