title: One-step synthesis and enhanced luminescence of Eu-doped BaF2 nanocubes.
abstract: Europium (Eu3+) doped BaF2 nanocubes were synthesized successfully by a simple method, using oleic acid (OA) as a capping agent. The structure properties were characterized by XRD, FE-SEM, and FTIR. FE-SEM analysis indicates that the prepared nanomaterials have nanocubic morphology with a side length about 150 nm and can be controlled well by adjusting OA concentration. Moreover, the photoluminescence spectra of the samples were investigated. The emission intensity of the BaF2:Eu3+ nanocubes have been enhanced greatly after modified with proper amount of OA, which is promising for new applications and optical devices.
