Abstract
| - Single-crystalline alkaline-earth-metal tungstate AWO4 nanorods (A = Ca, Sr, Ba) as well as a series of their crystalline solid−solution analogues Sr1−xCaxWO4 and Ba1−xSrxWO4 (0 < x< 1) with controllable chemical composition, luminescence properties, and structural morphologies have been systematically prepared using a modified template-directed methodology under ambient room-temperature conditions.
- The current report describes the systematic synthesis of single-crystalline alkaline-earth-metal tungstate AWO4 (A = Ca, Sr, Ba) nanorods as well as a series of their crystalline solid−solution analogues Sr1-xCaxWO4 and Ba1-xSrxWO4 (0 < x< 1) with controllable chemical composition and morphology using a modified template-directed methodology under ambient room-temperature conditions. Extensive characterization of the resulting nanorods has been performed using diffraction, X-ray photoelectron spectroscopy, electron microscopy, and optical spectroscopy. The composition-modulated luminescence properties of these alkaline-earth-metal tungstate solid−solution nanorods provide for a fundamental understanding of the intrinsic optical and optoelectronic properties of these systems, suggesting, therefore, the possibility of their rational incorporation into functional nanoscale devices.
