以氧化锌和石墨粉的混合物为原料，采用气相传输法制备了大量的氧化锌纳米片。纳米盘具有完美的六边形形状，对角线约为3 μ m，厚度为300 μ m。沿沿着+/-[10（1）相对于bar 0]、+/-[1（1）相对于bar 00]和+/-[01（1）相对于bar 0]六个对称方向的生长是有利的，而沿沿着[0001]方向的典型生长受到抑制，这直接导致氧化锌纳米盘的形成。讨论了其微观结构和生长机制。(C)2004年，美国物理学会。
Using the mixture of zinc oxide and graphite powders as source materials, zinc oxide nanodisks with bulk quantity were fabricated by vapor-phase transport method. The nanodisks have perfect hexagonal shape with about 3 mum in diagonal and 300 mum in thickness. The growth is favored along six symmetric directions of +/-[10 (1) over bar0], +/-[1 (1) over bar 00], and +/-[01 (1) over bar0] with the typical growth along [0001] direction suppressed, which directly leads to the formation of zinc oxide nanodisk. The microstructure and growth mechanism are discussed. (C) 2004 American Institute of Physics.
