Abstract:
By controlling the heating temperature of a mixture of In and Ge powders, we have obtained monoclinic In 2 Ge 2 O 7 nanowires at 600–700 °C, whereas we have produced cubic In 2 O 3 nanowires at 900 °C. The In 2 Ge 2 O 7 nanowires grown at 600 °C were terminated by Au-containing nanoparticles, giving evidence that the vapour–liquid–solid model is the major growth mechanism. With the growth process at 700–900 °C being dominated by a vapour–solid process, we have discussed the temperature-induced change in growth mechanisms. Photoluminescence measurements at 10–300 K revealed a broad visible emission centred at around 2.5 eV.
