Bell-mouthed single-crystalline tubular ZnO prepared by a soft solution method

Faceted single-crystalline ZnO tubes were synthesized by a simple soft solution method at 65  ° C. These tubes are of several micrometers in length and several hundred nanometers in diameter, with bell-mouths on each end. Structural characterizations using electron spectroscopy revealed that these h...

Description
Summary:Faceted single-crystalline ZnO tubes were synthesized by a simple soft solution method at 65  ° C. These tubes are of several micrometers in length and several hundred nanometers in diameter, with bell-mouths on each end. Structural characterizations using electron spectroscopy revealed that these hexagonal ZnO tubes were along [0 0 0 1] direction and side-enclosed by { 01 1 ¯ 0 } facets. The growth of ZnO in hydrothermal condition and the formation of this unusual bell-mouthed structure were discussed on the basis of the observation of ring-shaped nano-crystallites upon decreasing the time for growth.
