The LaBO3:Eu twin microspheres, composed of nanorods with high crystallinity, were synthesized by a facile hydrothermal process. Tunable luminescence property, which was observed by varying the excitation wavelength of the samples, was studied. Near white light can be generated for exciting at ∼370 and 390 nm. Because of surface defect, the LaBO3 twin microspheres present blue emission under the excitation wavelength of ∼330 nm.
High-crystallized LaBO3:Eu3+ crystals present twin microspheres morphology composed of thousands of nanorods, and the sample present tunable luminescence properties.Figure optionsDownload as PowerPoint slideHighlights
► Micro-nano structured LaBO3:Eu3+ crystals have been synthesized via a simple hydrothermal process.
► The LaBO3:Eu3+ twin microspheres were formed by self-assembly of the nanorods without any templates.
► Tunable colors (red, purple pink, pink and near white) can be achieved through changing the exaction wavelengths.
