Fabrication of Eu2+ Blue PL and Eu3+ Red PL Transparent Composites
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.
