Abstract

Eu-based composite films exhibiting PL properties were prepared by using europium nitrate and translucent urethane resin. The fabricated composite showed a red PL property with sharp peaks at 591 nm (⁵D₀ → ⁷F₁) and 615 nm (⁵D₀ → ⁷F²) attributed to Eu³⁺ as the emission center. The Eu³⁺ in the composite was reduced to Eu²⁺ by UV irradiation of the Eu³⁺-based composite. The Eu²⁺-based composite exhibited blue luminescence, with a broad peak centered at 478 nm.

Eu2+蓝色PL和Eu3+红色PL透明复合材料的制备

采用硝酸铕和半透明聚氨酯树脂制备了具有PL性能的铕基复合薄膜。在591 nm （5D0→7F1）和615 nm （5D0→7F2）处，Eu3+为发射中心，呈现出明显的红色发光特性。Eu3+基复合材料经紫外光照射后，Eu3+还原为Eu2+。Eu2+基复合材料表现出蓝色发光，其宽峰居中于478 nm。
