Abstract

In this paper, a systematic study of large-scale production of highly crystalline W ₁₈O ₄₉ nanoneedles with high aspect ratios using a simple tungsten metal reacting with water at 800-1000°C has been described. By altering the W source and other experimental conditions, we have generated W ₁₈O ₄₉ crystals with diverse morphologies, and needles with desired dimensions are achieved. The quality nanoneedles provide ideal samples for further property investigations. Possible growth mechanisms are discussed.
