Abstract

In this letter, the authors report the photoluminescence studies of Eu3+ doped Y2O3 nanorods, which have been synthesized by rapid microwave hydrothermal route within 6 min. The nanostructured Eu3+ doped Y2O3 is characterized by x-ray diffraction, transmission electron microscopy, and photoluminescence. The emission spectrum shows transitions from the excited 5D0 state to math (J = 0,1,2,3,4) levels of the Eu3+ ion. The most intense peak around 612 nm is due to the math→math transition, expected from the Judd-Ofelt selection rules [ B. R. Judd, Phys. Rev. 127, 750 (1962) ; G. S. Ofelt, J. Chem. Phys. 37, 511 (1962) ]. Photoluminescence measurements demonstrated that the nanocrystalline Eu3+:Y2O3 phase shows higher photoluminescence intensity.
