- Abstract
This paper reports an approach for enhancing the luminescent properties of Y2O3:Eu3+ nanophosphors with cellulose, using a liquid phase precursor (LPP) process. The nanosized ${\rm Y}_{2}{\rm O}_{3}\!:\!{\rm Eu}^{3+}_{0.06}$ particles showed a powder X-ray diffraction pattern, corresponding to the reference, and were highly crystalline. The grain sizes of the samples synthesized at 600°C for 1 h were estimated to be approximately 19 nm. The particle sizes of the samples increased with increasing synthesis temperature and the morphology was cleaned and without impurities. In addition, all the samples had a smaller particle size than that of the commercial product. The PL spectrum consisted of weak bands at 581, 587, 593, and 599 nm, corresponding to the 5D0 → 7F1 transition, and sharp peaks with a maximum intensity occurring at approximately 610 nm, due to the 5D0 → 7F2 transition of Eu3+. These results suggest that Y2O3:Eu3+ is a promising alternative red-emitting phosphor for high efficiency resolution display applications.
