Abstract :
Y2O3:Eu3+ inverse opal films were fabricated by the self-assembly technique, which had a lattice parameter of ∼260 nm and a photonic stop band at 520 nm. Near the center of the photonic stop band, both the emission intensity and the spontaneous transition rate of 5D1–7F1 transitions were modified. At the band gap edge, no obvious change was observed for the 5D0–7FJ spontaneous transition rate, however, the emission intensity of 5D0–7FJ (J = 0, 1) was depressed in contrast to the 5D0–7F2, which improved the color purity of the red emission.
