Abstract: Gd2O3∶Eu3+ nanorods were prepared via surfactant-assisted hydrothermal method. The structure and photoluminescence properties of the nanorods were characterized, and the growth mechanism was discussed. XRD patterns show that the precursors are hexagonal phase Gd(OH)3 crystals, and the samples calcined at 800 ℃ are cubic Gd2O3. TEM images indicate that the samples are nanorods with a diameter of 60 nm and a length of 600 nm. Photoluminescence measurements show that the Gd2O3∶Eu3+ nanorods emit Eu3+ characteristic red-light due to 5D0-7FJ transitions under 254 nm light excitation, which is different from that of the precursor. The results indicate that Gd2O3 nanorod is a candidate as host material for Eu3+ luminescence.

Key words: Gd2O3∶Eu3+, Nanorod, One-dimensional material, Photoluminescence
