| description |
<jats:p>Bi and Eu co-doped Y2O3 was used as a red phosphor with a very high efficiency
synthesized by the solid state reaction and co-precipitation The emission spectrum consisted of a weak
band at 581, 587, 593 and 599 nm corresponding to the 5D0 → 7F1 transition, with sharp peaks of maximum
intensity occurring at about 611 nm due to the 5D0 → 7F2 transition of Eu3+. In addition, the excitation
spectrum exhibited a broad band between 250 and 550 nm with peaks occurring at about 310 – 400
nm and a sharp peak at 465.5 nm. The relative emission intensity was improved by co-precipitation
synthesis as compared to solid state reaction synthesis. This implies that an appropriate
co-precipitation synthesis could improve the luminescent efficiency, particularly for the samples
prepared with the optimized firing temperature of 1100 °C.</jats:p> |
