Abstract
Eu(III)-doped Y2O3 nanorods were deposited onto a Si substrate by an electrospray technique and the photoluminescence imaging profiles of the electrospray film and powder formwere compared. The electrospray method enabled generation of a uniform monolayer film without much clustering of nanorods. Strong emission peaks were observed between 580 and 730 nm in response to an indirect excitation transition and assigned to D-5(0) -> F-7(J) (J = 0-4) transitions of Eu(III) ions embedded at the C-2 symmetry site in Y2O3. No emission in response to the direct excitation transition of Eu(III) ions was observed, while light was emitted from the Eu(III)-doped Y2O3 powder. Taken together, these findings indicate that the electrospray technique could be very useful for generating thin films for displays and sensors. (C) 2014 Elsevier B.V. All rights reserved.
