Abstract
- Dy 3+ -doped Y 2 O 3 ceramics were fabricated by Spark Plasma Sintering method. The effect of sintering temperature on the microstructure and the optical transmittance of the ceramics was studied. The maximum in-line transmittance of Dy:Y 2 O 3 ceramics with thickness of 1 mm was 74.5% at 574 nm when sintering temperature was 1550 ℃. The spectroscopic parameters were determined by Judd-Ofelt theory based on the room temperature absorption spectra. The peak emission cross section for the 4 F 9/2 → 6 H 13/2 transition was calculated to be 0.569 × 10 −20 cm 2 . The fluorescence decay curve and quantum efficiency of the 4 F 9/2 multiplet were measured to be 269.2 μs and 37.1%, respectively. [ABSTRACT FROM AUTHOR]
